Hi, had noticed a leak from under the water heater, just an egg cupful when heater turned on. Dealer advised it was a known fault on a valve and checked it out-sometimes swarf etc in the valve. Cleaned it out but still leaks so arranged for it to go in under warranty,( no spares available -but a known fault).Just had a phone call to say that wale have advised that it not an issue/fault and is a pressure relief when the water heats up there is some excess pressure and a slight loss of water occurs to reduce the pressure. So the valve does not need replacing. Its on an Eldiss Autoquest.
Anyone experienced a similar "leak", from a wale water heater?or am I having my leg pulled?

Hi Jim you should not get water leaking inside the van full stop.IF its from a pressure relief / blow off valve it should be piped to the outside ..... If they're saying different ???

Hi Terry
its not in the van, the heater is under the chassis. We noticed it whilst on hardstanding whilst on hookup at the dealers. It was only a small amount of water , but I had cause to question it, They advised it was a known fault with a valve and could be due to swarf in the system during build. They duly dropped the heater in the workshop and cleaned the valve etc, they didn't have any spare valve , although they di say it was a known fault. As we are at the soul meet in June I accepted for the valve to be replaced then as we are nearby. Today I had a phone call to say that they had contacted whale for a replacement valve under warranty etc and that whale have advised them its not a fault but due to a pressure relief when the heater is turned on.Therefore there is no need to replace the valve. There does not appear to be a relief drain pipe it appears to leak from the casing. Which I will question tomorrow when they call me back.( it was just a girl service desk receptionist that phoned me) I just put up this post to see if anyone else had experienced the same. When we are on hard standing next and have the heater on I will measure the amount of water that's leaked. It doesn't appear to be much hence my query.
Jim
Ps the pump doesn't run when it leaks, not like a water pipe type leak

Sounds plausible Jim and if water pump is not kicking in its not loosing pressure....would not worry about it.especially if its on the outside

Hi yes we've got the same problem, we spoke to Whale and they gave the same explanation that it is designed to release a bit of water when the pressure builds (heating engineer friend confirmed this makes sense on such a small cylinder).
HOWEVER the drip has persisted and eventually trips the RCB on the hookup supply, I spoke to whale again and they said that if there is an excessive amount of water coming out of the the pressure relief valve (I sent them a video and they admitted it was excessive) the water gets on to the PCB board that's located right next to the water release point which as Jim says literally comes out of the casing and not a pipe. We are in a hard water area and running descaler through the hot system every couple of months has solved it but now its so bad even that doesn't work. Terrible design, we have been advised to get a Whale engineer to look at it but as we live in the van for work the covid situation means we are stuck, its so bad now we have to run the hot water on gas to avoid tripping electrics (pump runs every 10 minutes or so). I'm going to order a new valve and hope for the best as and when I can get an engineer to fit it. Caravan is an Elddis Avante 2018

Not had any issues with ours,it still drips when we are parked up and the heater is on but it's external and through the vent hole so no problems.no sign of scale etc .currently fully drained and on the drive awaiting our next venture out.
Ps pump does not come on when we see the drips etc.

I have the same van as you ( Compass Avantgarde 175 ).... I've not had any issues with water heater. I've found the Whale system to be great actually, but, I will keep an eye on it now that you've mentioned it..

I have a similar whale water heater problem on my Elddis accordo 120,2018 motorhome, the heater stopped working and the dealer sent it to whale to be repaired /replaced under warranty,whale refused to repair saying the pcb board was wet caused by water from a external source ? they did not mention that a pressure relief valve could possibly drip onto the PCB board, I was under the impression that a water heater was a sealed unit ? and is attached to the under side of the Motorhome. I cant understand their stance in refusing the repair .

Our Whale water heater drips when switched on. As the water heats up it expands slightly resulting in some drips from the pressure relief valve. Our previous Elddis also did this. This is quite normal but it should not happen when the water is cold.

don’t own one yet
We’ve the same problem on an 2018 elddis avante 840, at times water floods floods out other times a constant drip that causes the pump to constantly turn on and off, had a ‘caravan engineer’ look at it three times now and still the fault persists, absolute rubbish system!

We have a 2013 Elddis 175 and we have had no problems 8 years on, I suggest the maybe try and find a competent caravan engineer as the one you have use three times would not appear to be up to the job. (y)

Got an Elddis Autoquest 185 (Majestic) with the same problem. Not all the time but certainly often. Water heater on, drips a lot and pump has to just kick in every 15 to 20 mins. I think the pressure relief valve isn’t reseating properly when it properly blows. I found if you just press your finger fairly lightly on the valve (looks like a small hole where the water is coming from) it squirts water out at pressure and this sometimes clears the seat which then resets itself and stops dripping. This hasn’t stopped it doing it again at other times but has helped stop a grass pitch getting too muddy. WARNING don’t get your face too close it is hot water coming out.

There seems to be many occurrences of this problem that Whale don't want to admit is a problem!

We have a 2018 Elddis Autoquest 155 and I'm still waiting (2 weeks +) to hear from Elddis/ Whale whether this will be fixed under warranty for a SECOND time!

The first time, is basically leaked constantly and wouldn’t work on the electric or gas. Whale said it was frost damage that had damaged the PCB at first but we successfully managed to get it repaired after it was sent back to Whale (it may have actually been replaced!). I wonder if they spotted a faulty pressure relieve valve at that point???

Now, 14 months later what started as a trickle a few weeks ago with the pump kicking in every 20 mins or so, it's now a constant drip, drip, drip that means we can only switch the pump on when we need water. It also makes travelling a bit of a lottery as we've been caught with an empty tank on two occasions now.

We’re about to head out for a week so the only thing I can think of to stop us running out of water is to put a tap before the cold water inlet and only fill the heater when we need hot water. Or any other suggestions would be welcome! Thanks, Martin
