Hi
We have a vaillant turboMAX 828e
Never had consistent temp water from shower/taps but recently got worse, water now gets up to temp then goes cool, then rises and continues this loop during use.
The last 5 stored fault codes are:
1 - F.24
2 - F.22
3 - F.29
4 - F.22
5 - F.22
When opening a hot water tap the boiler display shows the following:
S.30 - Green light on
S.13 - Green light flashes
S.13 - Yellow light illuminates, green light flashes
S.14 - Yellow light illuminates, green light flashes
S.10 - Yellow light off, green light flashes
during this time if i press "i" the temp is rising fast to 95 degrees then dropping back to 70, then rising again to 95... the loop continues
CH is fine and this seems to happen weather or not heating is on.
I had noticed the pressure guage was low (below 1bar) so have topped up the boiler to 1.5 now but this didnt help.
From the research i've done (don't really know anything about boilers other than what google has taught me in the last week) it seems to indicate the plate heater exchanger could be clogged up.
Can anyone verify?
Is this a part a boiler engineer would usually try and dismantale and clean before replacing.
Ive been quoted about £250 + vat for a new one by one company i contacted via checkatrade- seems a bit high to me? They also didn't confirm if it was worth cleaning it first.
I think the part number is 65131, googling that or '828e plate heater exchanger' returns many for around £100 or less, some around £60
Money is tight and im causious of getting someone to look at it who's going to take the most expensive approach to repair
Can anyone recommend a good honest vaillant service engineer in southampton, hampshire area, or suggest what anything i could try myself or expect to pay?
Would a fixed cost service resolve this sort of problem?
The boiler was installed in 2004/5 i beleive, we moved to the property this year.
Many thanks for reading all this and any help
