Grundfos SCALA2 Questions & Answers
Verified
Hi, I am in Australia and have a Grundfos Scala 2 which has failed. Our retailer has been very helpful so far as the pump is outside of warranty (even based on the date of purchase), as we believe it doesn’t meet ‘reasonable durability’ expectation under ACL (purchased 5 years ago by our builder but installed in 2022). That said, retailer just came back saying that Grundfos have advised the warranty starts from manufacture (2019 as we have found out), which doesn’t seem right. We’ve been offered a discount on a new pump which is appreciated but after having spent $300 on getting it looked at I’m wary of buying another one with such a short lifespan expectation
Hi Anastasia, Thank you for taking the time to share your experience. We’re really sorry to hear about the trouble you’ve had with your SCALA2, especially after only a few years in service. We absolutely understand how frustrating this is, particularly when you’ve already invested in inspections and are now weighing up replacement options. Given the unique nature of your case we'd like to look into this in more detail for you. It is important for you and our customers to know that many improvements have been made to SCALA2 over time and we released a new model in July 2024 in Australia and New Zealand that is both much more robust and durable as well as even more quiet and efficient than before. Please send an email with photo of your nameplate, proof of purchase and existing correspondence with the retailer and Grundfos to marketing-au@grundfos.com and we'll be in contact with you shortly. Thanks again for raising this—we appreciate the chance to make it right. Kind Regards, Aaron
I'm now on my 3rd Scala 2, They are a great pump but here in Indonesia it's hard to get a reliable or knowledgable service person, each pump that we have owned have had different issues but the latest pump does not behave as the previous pumps.
Our system is as follows: the town water supply feeds into a 2,000 litre water tank approximately 1 metre above ground level, water is then piped to the Scala 2 and is then pumped to the house through a large capacity water filter and UV purifier. We also have a solar hot water system that feeds to the house via a Grundfos Home Booster UPA 90.
With our previous 2 Scala pumps the water pressure remained constant, however with the new pump installed the cold water pressure drops after about two minute and all we get is hot water, (which can be very dangerous considering the hot water temperature can reach over 90°C), after about another minute the cold water pressure returns to normal, then it cycles again to with approximate 1 minute intervals.
Please advise.
Regards Marc
Hi Marc, This Australian Review site is monitored by the Grundfos Oceania Marketing team. Unfortunately, we are unable to answer technical questions of this nature on this review site. We would suggest you contact the installer, to check that the pressure setting on the SCALA2 is appropriate for the application and matches the previous settings of the other pumps. If the installer cannot or will not help, then please contact an Authorised Service Partner in Indonesia. external link
My pump is leaking water. I've been advised it you should replace it as it is now being recalled. How to I arrange this.
Hi Teresa, If you are located in Australia or New Zealand there is a 2 Year Warranty on this pump, starting from the date of purchase. If your pump is within this Warranty period, you should contact the Grundfos Authorised Dealer where you purchased the pump to have it replaced under this Warranty. If you are located outside of Australia or New Zealand who will need to contact your local Grundfos Service Department office to find out the local Warranty status. This pump has not under a mandated recall in Australia or New Zealand. Regards - Grundfos Marketing Oceania
I just have a question about how the Scala 2 pump behaves after the power is cut and then comes back on? The reason being that I'm planning to put it after an inverter that will be on periodically and the pump will be hard to get to physically, I noticed it has digital buttons so I would just want to know if I have to push the ON button everytime after I start the inverter
Hi Christoffer, As long as the switch is on at the power socket onto which the SCALA2 is connected, the pump will power on when power supply returns and then demand is created (tap turned on). No need to press the power buttin on the pump control panel. NB: If the water source is below the level of the pump, ensure you have the original non-return valve in place behind the inlet connection of the pump, to ensure water is retained inside the pump when the pump is off. Otherwise the pump may need to be re-primed before re-starting. Other original settings of the pump are retained despite any loss of power. Hope this helps.

Hi. Installed a scala 2 pump in2020. Now it’s leaking out of body of pump. Sent a request to replace as I thought was still under warranty only to find warranty was out in September 2019 Warranty it seem only from day of manufacture???? Anyone know any different.
Hi John, The Grundfos Product Warranty covers the pump for 2 Years from the date of purchase, not the date of manufacture. Here's a link to the Consumer Warranty Document on our Australian website: external link If you had purchased the pump new in 2020, the Warranty would have covered the pump, under the conditions of the Warranty, until the same date in 2022. If you were informed by one of our Grundfos Authorised Dealers that the Warranty period begins from the date of manufacture, we would appreciate knowing who the retailer was, so we can make ensure they educated about our consumer Warranty. Regards, Simon Tynski - Grundfos Ocean Marketing
Hi Thank you for your reply. I’m in Ireland and the warranty was 5years on this pump. So if install this pump in 2020 it’s warranty would not be up until 2025 I was told it was from date of manufacture which is sept 2019
Hi John, I wasn't aware of your location, so this does change things. Every country has it's own laws and legislation covering consumer protection, so I imagine the laws in Ireland aslo difer. I went to the Grundfos Ireland website and found the local Warranty information. Here's the relevant clause from the ireland Warranty section.
WARRANTY PERIOD 10.3 For the warranty to apply, customer must notify Grundfos of a defect without undue delay after customer becomes or should have become aware of the defect, and (i) for products, customer must in every respect notify Grundfos no later than 24 months from the date of installation of the product, however not exceeding 30 months from the date of production, and (ii) for services, customer must notify Grundfos no later than 24 months from the performance of the services (the “Warranty Notification Period”).
Here's the link to the full Terms and Conditions of Sale in the Republic of Ireland according to the local wwebsite. external link
If you wanted to get clarification from Grundfos Ireland direct I would suggest you contact the Local Service Dept about your SCALA2. external link

Hi , I have scala 2 pump around 2 years old which failed a month ago, open up and found one of the chip on the motherboard has been burned off. (next to the big capacitor). I am wondering if this can be fixed by just replacing the chip or have to replace the whole motherboard? if to replace the motherboard , how much will it cost?
Hi Alex - The motherboard and it's individual components are unfortunately not available as a spare part/s, however, if your pump is under 2 Years old you normal product Warranty is still applicable and you will be able to get a replacement unit. Maybe firstly check the invoice from your supplier. If in Warranty please contact the retailer who will assist with the Warranty claim.
If your SCALA2 is out of Warranty we can still assist, if you send us the name of the reatiler you purchased the product from and a picture of the "name plate" on the end of the SCALA2 pump. (The round plate with all the writing on it). Send this info to markeeting-au@grundfos.com and we will try to assist in getting your pump back up and running. Regards SImon Tynski -Grundfos Marketing
Thanks Simon, Yes will do.
Hello Grundfos Team,
I am writing to inquire about my Scala2 pump which is two years old and currently experiencing lower pressure. The technician who inspected the pump suggested that it needs to be replaced since it cannot be repaired. However, I am concerned whether the pump is still under warranty or not.
Thank you for your help.
Hi Bala N., thanks for your enquiry. Questions on this review website are handled by Grundfos Pumps Australia. If you are based in Australia or New Zealand we would ask that you contact the pump dealer where you purchased the pump and they should have a record of when the pump was purchased along with your proof of purchase. They should be able to help you determine if the pump is within the 24 month warranty period. Kind Regards, Aaron
I purchased a Scala2 11 months ago--it has worked perfectly. However, was wondering is there any service required on a Scala2 on a yearly basis. I was told I need to check the air pressure on the pump (should be 25 pounds); is this correct? Is any other service required on an annual basis? No mention of this in the manual I got with the pump.
No
No on amy maintenance, or no on having to check to see if air pressure is 25 psi? Thank you in advance for any insight.
Hi Thomas There is no real service schedule, unless "winterising" the pump in conditions where the water inside the pump may freeze - if so refer to the instructions in the I&O. Otherwise, the factory pre-charge pressure in the internal tank is 18 PSI, not 25PSI, so 18 PSI should be maintained unless the pressure was increased at installation. If it was increased to 25 PSI at installation, then this should be maintained to provide the same performance and pressure cut-in point. Under normal circumstances the pressure will not reduce/leak over time. Hope this helps.
Thank you. You raise an interesting point, so normally one would not even check the internal tank unless the pump were continually starting and stopping.
Hi Thomas - The tanks doesn't need checking unless, as you say, there's some cycling which is not explained by a leaking taps or other outlets. Under normal operating circumstances the pressure in the internal tank should be set to approximately 70% of the required pressure set using the control panel on the top of the unit.
Theres always leak in the bottom of the scala. In the strainer at the bottom. I change the gasket or the o ring.. theres a leak again and the o ring have a damage..
This is a design fault of this product, read the negative reviews
Why the big o ring near in the impeller always damage when i put it back..
I have a Grundfis SCALA2 pump is now not working on the red light on and I need assistance here please
Hi Newman, we're sorry to hear you might be having some trouble with your SCALA2 pump. We suggest you consult the user manual, particularly pages 16, 21, 22 to identify which red light is on and what that light might be indicating and contact the dealer you purchased the pump from as your first port of call. If you have worked through the problem with the dealer and you still don't seem to be getting anywhere then we would suggest you contact the nearest Grundfos Service Department to you. Where are you based? Kind Regards, Aaron
Red light on Scala2 pump stays on. what does this indicate?
If the two red lights flash in series of two, then the sensor is defective, or its electrical connector is installed incorrectly.
I have a Grundfos Scala 2 at my cabin. I'm getting ready to close up for the winter. Any recommendations on draining the pump or is disconnecting enough? Mild winters, Vancouver island, BC Thanks!
Hi Marlene, thanks for your enquiry. ProductReview.com.au is an Australian website so your question has actually come through to Grundfos Australia. Admittedly, your scenario, and the problems you are trying to mitigate against aren't ones we commonly experience :). However, the principles we can share are going to be applicable. You need to unplug the pump from its power source (de-power it), drain the water out using/undoing the drain plug on the front at the bottom of the pump (below the bottom connector). Then unscrew the priming plug at the top of the pump and blow it out with an air compressor to try and get as much of the water out as possible. And just remember to reprime the pump with fresh water next year before you use it again. All the best, Aaron, Grundfos Australia.
We had a pump installed two years ago. It is now leaking from the bottom of the pump. We have replaced the seals and it's still leaking. It is out of warranty by three months. Is there anything we can do beside purchase a new pump?
Hi Billie, Sorry to hear of the issues with your SCALA2 pump. To have your pump assessed please send a photo of the Pump Name Plate (the printed plate on the end of the Pump), the store where you purchased your pump from, your contact details and a detailed description of what has occurred (similar to what you have written above) through to GPA@servicesupport.grundfos.com so our service department can review the matter further. Kind Regards Grundfos Marketing
Hello, I purchased a Scala2 as recommended from my Plumber to help increase the water pressure in my home. As soon as the pump was installed, I did notice an increase and am happy with that. The problem is that water is pooling under the pump. The pump is not leaking but the water continues to pool. After 2 months, there was so much water it is now accumulating in the garage and draining in front of the driveway. I called the plumber to see where the water is coming from. He disconnected the pump and now there is no pooling. I am still not clear where the water was coming from. I have disconnected my pump and the pressure is low once again. I do not know what the problem is, and am hopeful someone here my know?
Hi Elcid, In theory the pump may leak a small amount of water on initial start up and reduce ‘over time’, however if it’s continuously leaking water it should be replaced. Please return with proof of purchase to the Grundfos dealer you purchased it from. Kind Regards, Aaron
Had flow meter replaced a couple of days ago. Green pressure light is flashing. Haven’t ever noticed that before. Water inside house doesn’t seem like we have the pressure like before. Any help would be appreciated.
Hi Wendell, without knowing the full set up and situation, I'm going to need to make some assumptions. I'm assuming the flow meter is not part of the pump so either that is restricting the flow or the pump set point or operating pressure is set too low. It should be 300 kpa or set between the 2nd and 3rd horizontal pressure markers on the pump. If you continue to have an issue after checking/correcting this you may need to get a plumber out to see what the problem might be. Kind Regards, Aaron
I want a pump for off-tiny house. There's two showers (indoor and outdoor), a sink, a handbasin, and in future I hope a spa pool. But all small, not lengthy pipes. Plumber recommended Scala2 3-45. Do you think this is suitable - will the variable speed reduce demand significantly on my existing batteries? Will it be quiet (ie not audible from inside house about 7metres away). Has the leaking problems discussed in the reviews been resolved?
Hi Natalie, how big is your battery? No, the leak problems have not been resolved (read my * review). We had to wait over 2 month for a replacement for a identical pump. Get a cheaper pump, place it in a DIY box 10-20m from your house and buy yourself a more efficient fridge for the money you saved.
I have a SCALA 2 pump which failed in less than a year, it leaked everywhere. I have received a replacement pump same model which now needs to be installed. Has this issue been resolved by Grunfos? It sounds from all the comments above to be a very common problem. I'm concerned that this will happen again with the new pump. Also, I have paid a plumber to install the original pump and now again I will pay a plumber to install the replacement. Have modifications been made to the new pumps to stop this occurance??
A modification has been added that is supposed to fix the issue. Unfortunately the modification (two metal brackets) do not address the issue at all. Whoever designed those brackets has obviously absolutely no engineering skills what so ever.
Hi Mary, we can appreciate your concerns and it's completely understandable that if you've had a problem with a pump, you want to make sure that you're not going to have the same problem with its replacement. Please send an email to marketing-au@grundfos.com with details for how to contact you directly so we can discuss your situation further. Kind Regards, Aaron
Also have a scala2 here in Amsterdam and leaking via the insectfilter since monday. Drip drip drip and now damage at the neighbours and my house. The cause is apparently two damaged rubber rings in the pump, caused by a faulty manufacturing quality issue.
Found a video clearly showing the issue and that it is a manufacturing issue which breaks the rubber rings inside. See the video, cann't understand the language, but shows the issue crystal clear. https://m.youtube.com/watch?v=Ad9PP6Uq_LE
Grundfos must know of this issue but still is not recalling the Scala2 globally and have it replaced.
Having issues with the pump , checked water supply from tank is at the pump , but pump will not start , any recommendations on what to check . Looks like there is a non return valve on the supply side ?. It's been installed for 18 months , no leaks , but now just sits there . Have carried out a manual reset but nothing apart from 2 red segments on the running led light on top ??????, any advice would be appreciated .

Dear Grundfos, we are discussing technical issues here, so we need technical advice from a "technician" not from the marketing or accounting department, or are you making fun of us like you did with this pump model?
Hi, does anybody know from wich week number in 2021 Grundfos switched production from the scala2 3-45 with water hammer and leaking problems to the new reinforced model with the same name scala2 3-45?
Hi Kjell Aage O., We have experienced some issues with SCALA2 units built prior to the end of 2019 suffered some leaking issues. If you need to have your pump assessed please send a pic of the Pump Name Plate (the printed plate on the end of the Pump), the store where you purchased your pump from, your contact details and a detailed description of what has occurred through to GPA@servicesupport.grundfos.com so our service department can review the matter further.
