Ok, last week I added an extra radiator to my system.
it it had recently bee taken out of a friends house.
Since then I have had continuous problems with my vaillant ecotec 28.....
i have bled the system countless times, changed the pressure sensor, cleaned out the filter and checked the expansion tank pressure.
it will run with one radiator on but as soon as I turn the others on it crashes and shows the f75 code.
water temp is also erratic.
anything else I should try before calling out a engineer?
thanks, matt
