Alde wet heating - bugger bugger bugger.

[glascoed]

Well technically it's a Truma Aquatherm but made by Alde.

Van will be used as an annex for family over Christmas so I thought I'd check it out and air it today, under floor heating been on all day.

Couldn't hear the pump although in bare feet there was some heat coming through the floor. Couldn't see water level in the viewing window. Assuming it must be low i took the access panel off. Water level was way over max (i hadn't topped up!!!) Guess about half litre.

I've had the van 20 yrs and usually check level regularly. Didn't this time before switching on!!!

I'm assuming there must have been a leak, the level fell below min and the damn pump has been pumping air into the system all day. Has the pump stopped cos level too high?

Could there be any other explanation? I'll let it cool over night and try to bled it with the only bleed ripples I know of. On the rads behind the cab seats.

Never had to do it before. Any tips? Apart from checking the bloody level BEFORE switching on.

If the level is ½ liter above full how can the level be low at the same time?

I think he’s suggested, it’s pumped air into system so level is showing above full mark

So water level is low but showing high as it has air in the system
