Can't trust it to actually work
Worked fine for one summer of watering, now only works about 20% of the time. Most times when it comes on (either manually or via schedule) the display indicates that it's on but no water flows. Started happening intermittently but now happens all the time. Have changed out batteries to no avail.

Zero star rating
Bought first unit from Bunnings. Zone 4 solenoid not functional. Returned and swapped with a second unit. Zones 1 and 2 not working! Very frustrating. Wish I'd seen this website first. Looks like it is hard to find a decent 4 zone programmable tap timer that actually works.

Needs no star rating
Bought from Bunnings worked great for two weeks. Then solenoids failed in 2,3, and 4 so I could only use the first line. I wished I’d seen this website before I purchased this and saved my time and money.

Waist of money
We have now got three of these things. They work on occasions most of the time they are useless attachments on the tap that waist more time fiddling with then it would take to hand water. DON'T WASTE YOUR MONEY.

Not worth 1 star. Complete rubbish.
I have now had a gardener, a landscaper and a handyman all attempt to get this completely useless instrument working. When I add up my time invested and theirs, it demonstrates what a poor choice I made. Do not waste your money or time!

Have had one for over a year so cant return now, but manual watering doesnt work and program watering doesnt always come on, bought another one 2 weeks ago for the front yard, the manual watering and programmed watering doesnt work so will be taking back asap, waste of money specially when it cost $160
Random failures and then complete failure
I want to like this product because it is simple, light, easy to install and program and comes with a 2 year warranty. For the short time it is fully working, it's good. However, the reality is that like all the other reviews you'll find of this product, zones stop working for no apparent reason, meaning that some watering cycles may not start and manual watering won't work for those zones. I saw zones operating if they started due to a scheduled watering cycle, but moments later they wouldn't start if you set the zone to manually on. Sometimes...zones would only work if manually started. The display will tell you the zone is on and water is flowing, and you'll hear the solenoid click, but no water will flow. Sometimes turning the tap off and turning the tap back on at the exact moment the solenoid clicks worked--sometimes it didn't help. I had these problems fairly soon after purchasing the product and after fiddling around with it, I finally managed to get it in a state where water was flowing on the programmed schedules for about 2 months. Then 3 of the 4 zones just stopped working altogether and no amount of fiddling around could get them working again. Returned for a full refund so I could buy a reliable alternative.

Rubbish, like everyone else suggest.
Like all the other poor reviews, says it is watering in either auto or manual but no water comes out. We had it set while we were away and came back to carnage.
Avoid or at least keep your receipt, you'll be returning it within 3 months.

DON’T EVER BUY
This product does not deserve 1 Star.
Like most people it says it’s watering but nothing happens. Bought it today and immediately failed, never worked, replaced 3 hours after the original purchase and the second unit worked once and then nothing.
This is beyond a joke considering it is not a cheap timer.

I bought this to water a property I own in the country that I do not live at . Like the other reviews , the valves to not switch on even though the screen shows water is on. This is both on manual and auto . So disappointed when you see your garden dying because this thing does not come on. I’m astounded that this is a known issue for a few years now and it is being still made and sold . What a waste for such an expensive timer

It indicates it watering but no water
This is garbage. Purchased both th 200 and 400 series. 200 has been swapped out once and now have the same problem with the 400. It doesnt water even though it indicates it is. Also zone 3 manual operation doesnt work on its own.

Does NOT work! Did not come on the morning we were to go away and could not even get it to function on manual. Went online to check reviews and low and behold people with exactly the same problem. NOT RELIABLE!

Don't waste your money
Had one of these which worked well for 2 weeks then a hit or miss situation, valves wouldn't open on 2 of the outlets. After re programming several times trying to get it to work returned it to Bunnings for a replacement, same situation one of the zones not functioning at all. This timer is not fit for the purpose intended, how could you possibly go away and rely on it working. Having now read other reviews Holman must be aware of this inherent fault and should be doing something to rectify the situation. A pile of rubbish!

Had one of these units recently and have had to replace it twice in the space of 10 days. Installed them for a new lawn so had to have a functioning unit. It failed almost every time, either one of the four stations would come on and not the others, a couple of times no stations would come on at all. Even had issues turning it on manually. Constantly bleeding the unit as per the instructions. Holman are obviuosly well aware of this. Very frustrating and after the second unit failed. Also had purchased a Holman manual four hose splitter brass unit that worked for 5 days and then water spewing out the sides. I chose Holman because they're an Aussie brand but certainly won't purchase or recommend this brand.
Bought this last weekend. After the initial testing, we set it up to turn on at 9pm at night. Zone 1 didn't turn on. Zone 2 and 3 did. The Water symbol appeared but the valve did not open. To make it work we had to unscrew the whole thing off the tap and then re-attach and then water zone 1 manually.
After 2 days of this, we return it to Bunnings to replace it, only to be told by a Bunnings staff member that they are a bit hit and miss.... for $170 they need to be hit not miss.
Second one.... worked great for 2 days. Zone 4 we kept free so we...

We live 350km away from store... took it home... programmed it and only 1 water station worked properly. First station would sometimes allow manual override and other times it would not open the valve. Station 2 worked how the product should have but then station 3 and 4 did not open the valve at all. I am worried about getting a replacement and having to drive 700km round trip to be disappointed again.

Lasted 12 months
Disappointed to read these reviews as mine has now done the same.
The system has been resetting its time, so unless i check it the system wont come on when required. Middle of summer? Not ideal. Then when i use manual on, put a time in, it starts, i can not use manual off i just have to wait it out... but not the time i input, whatever time it feels like. Sometimes a half hour, sometimes ten minutes. I have tried new batteries even though it made no indication of being low. Still no joy. Sometimes no water comes through (at least once a week)... has anything been changed since the below reviews? Very unsure if i should replace it with the same if i will just get the same model.

No Water Flowing Through When Programmed & LED Display Script Lights Up & Timer Resets
Firstly, when these units work, they work brilliantly. But..there is a BUT though. Initially thought it was something I was doing as when I first installed the 400, it intermittently did not allow water to pass through the Water Whiz 400 it when programmed but it has now become more regular. The display shows the tap with water flowing symbol in the top of the screen, the timer clicks to open but no water flows through the designated outlet or any of the other 3 outlets. I also noticed that all the LED screen script light up & the time of day r...esets itself. I also have a Water Whiz 200 that has started to have the same problems in the past month. I will be looking at taking both units back to Bunnings for a replacement of both units. If they fail after replacement I will be getting a refund. These units are not cheap items with the 400 at $149 & the $200 at $99 so should last years at least but look only to have lasted 10 months. I have both units in weatherproof enclosures to protect them from the weather so weather damage is not an issue. I will be looking at other units if these fail again. December 23rd 2019 Update: Holman pls explain why solenoids continue to stick shut I have a Water Whiz 200 & 400. Let me say, these units work brilliantly..... when they work. I have just replace the failed 400 unit b/c the solenoids on outlets 2 & 4 would not open even though the solenoid made a click sound. This is an inherent problem with these units as indicated from the reviews. What is Holman doing to rectify this issue as I will be returning my units if they fail again & get a different suppliers unit or a refund. December 24th 2019 Update: Warranty replacement unit failed after 10 hours being reinstalled UPDATE: Installed the new warranty replacement Water Whiz 400. Tested it with no problem, all solenoids worked manually. Programmed it & waited for the scheduled watering to occur. NOTHING .... and the unit is only 10 hours installed. Checked the unit operation & NONE of the solenoids would operate even though they clicked signalling they were trying to open & the water flowing symbol was displayed on the screen. Reset the unit but still none of the solenoids would open. Checked the delay setting but it was 0. Reduced the pressure on the intake but still no operation. Holman, what is the issue with these units? Why are the solenoids not operating reliably? This is the fundamental system for operation. There is no way you can set & leave secure in the knowledge that they will operate as required. This replacement unit will be going back for a refund & I will be looking at other options.

Nice interface and flexibility. Would be perfect if it allowed water to pass through itself.
Loved the user interface and flexibility of programming. Four watering zones each with 4 individual programmable runtimes including frequency (select which days to water or the option to choose every second or third day) gives heaps of flexibility.
Unfortunately after a week it simply stopped working reliably. Had it replaced and that unit failed within a couple of days.
Questions & Answers
This is my second Holman Water Whiz 400 and I am having the same problem. This one has served well for nearly 2 years. I have three outlets connected. Of late the Holman is leaking once again from the neck of the unit. The flat top of the white neck has broken off from the body of the main neck. Can this part be replaced? Or do I now need to buy a new one again?
I Have a Waterwhiz 400 and the zone #1 will not close. I have tried the reset function, the manual running of zone #1 for 1 min etc, but it still will not close zone #1. When I run the manual function on zone #1 it almost instantly shows reset on a blank screen.
Your earliest attention will be appreciated.
Hello Byron, for product support, please contact us on 1300 716 188. Thank you, your Holman Team!
My Water Whiz 400 keeps resetting the time by itself. I have it on Auto, when I come back to it is on 'set time' and the time has changed.
How can I stop it doing this please?
Hi Nick, I have never experienced this issue myself. Have you tried to reset the Water Whiz and try setting the time again. To reset it, press and hold the OK button till the time is reset to 7.00am. The unit will be in default settings now. Also make sure that your batteries have a good charge and are not close to being dead.
Dear Dr DG
Thank you for your prompt response
I renewed batteries (they seemed OK) and reset as you suggested. Clock seems to work now - and switches on at the right times etc.
It runs the first channel, then gets stuck on the second - won't send any water now even on manual to channels 2,3 or 4. Channel 1 works fine.
Any ideas? Maybe a malfunction?
