    Vaillant ecoTEC plus 837 R1 with persisting F75 fault

    I will check the vessel. After installing F75 kit is it best to leave the bottom sensor connected or it's best to disconnect it's plug?

    Vaillant ecoTEC plus 837 R1 with persisting F75 fault

    I noticed that if the F75 starts kicking and if after the first reset F75 returns, it makes it calm down if I top up. Last time boiler was at 1.7 bar before the first F75 kicked in. Generally speaking Vaillant have different fault code for low pressure and the boiler can work very well with 1.2...

    Yes, every three months or so, and it does seem to keep F75 away for a while, we are now on 1.8 bar when cold and 2.1 bar when hot

    Vaillant ecoTEC plus 837 R1 with persisting F75 fault

    All those parts has been replaced in the course of 5 years not all at ones, and from different reasons, but the F75 has been creeping out all this time, some times the fault would be gone for months so you think that it was cured.

    Clicking ticking sound from under the floorboard. HA4 post code.

    Hi We have Clicking ticking sound from under the floorboard, that's when the heating system is working. We have already removed the floorboard and replaced some pipes in the area of the noise. Would anyone covering HA4 post code like to take it on? Thanks

    Clicking/Dripping sound near the radiator

    Can't hear the boiler working as it's at the other end of the house so can not tell if noise start when it kicks in. Probably not a drip as we don't see dump at the ceiling down below, and it does not loose pressure. Clicks come in batches in every minute or less.:speechless: Boiler by the way...

    Clicking/Dripping sound near the radiator

    Thanks We have lifted the floorboard, looking at the pipes hearing the tickings but could not possibly say where exactly is it. we ended up replacing that part of the pipes with new plastic ones, the tickings has now shifted by 2 feet but they are still there.:smile5:

    Clicking/Dripping sound near the radiator

    Have anybody found a cure to this? we have exactly the same clicking noise from under the froorboard, could be hundred of them in an hour and could be a lot less, there's no pattern to it, we have just moved into the house so we don't know the history. Thanks.
