I have a Ashbys heat exchager and it keeps on tripping the fuses an both domestic and commercial properties, the thing is it dodn't do it all the time, some properties it is great, wondering if anyone has come across this problem, also does anyone service or repair them.

William,

There are many previous points raised about this product.

What is happening is the steam is getting, into the electrics, causing the tripping. When it dries out it will work o.k, until the steam comes back.

We found when PAT testing that, it would fail on insulation testing, further examination of the internal cables, found these had begun to break down, so these had to be replaced, although the machine had very little useage.

I gave up with the supplier, and have stopped using it when in people's houses for fear of either getting a shock or giving someone one, as not all fuse boards trip out.

I had this problem once.

I do not know if this was the problem but I came to the conclusion I was keeping it in damp  cold conditions and the electics had got saturated with condensation.

I was told to dry out with hairdrier I have not had a problem since but my heart always stops when I switch it on

I know it a silly queation but how did you dry it out with a hair dryer ( did you take the casing off)

[Ian Gourlay]

I was told to take casing off but being lazy and not an engineer I decided not too so just used hairdrier for about 15 minutes on outside of case, left machine in a warm place over night and all has been well since.

Why I have come on line again is I forgot to tell you to use a plug in Circuit breaker.

However on reading the previous post to my first one perhaps you had better get a PACT test

I use a similar heater.
I presume that these heaters have a safety pressure relief valve to get rid of excess pressure also a non return valve to stop the water going back to the pump. (The one I use has these.)
When they are first turned on the water is obviously cold. Water expands when heated. This puts the pressure up in the unit and a lttle water dribbles out of the safety valve. The outlet from this is inside the case- so you get water in the electrics. This did not happen when the old rubber hose was used as the pipe would expand to take the excess. Neptune hose won't do this hence the problem.
Perhaps the manufacturers will tell us whether we need the non return valve.
If this can be taken off then the excess pressure would be vented back in the machine via the pump pressure reducer.
The amount of excess water is very small as water does not compress and the pipe won't expand.
I have had difficulty pressing the wand valve as the pressure has been in excess of 400 psi with the pump set at 120.
