Hi All,
looking at a vaillant ecotec plus 824. It is coming up with f75. This seems to relate to low pressure and pressure sensor. Have changed the pressure sensor, checked the pump, change the divertor valve ( that was original fault). System pressure is 1.5 and still no joy. Hot water fine. Starts the sequence but fails when it gets to fan and pump running (s05) then fault code F75 appears. Checked the manual and vaillant web site and they say could be a number of related issues!
i am now think PCB board but any ideas before this is bought.
thanks
