Hi all,
After replacing the water pump in my boiler I have hot water but no heating.
Status shows code s.30 although there is a demand for heating. Any ideas?
Thanks in advance.
Can anyone help?
I replaced the water pump (whole) in my vaillant ecotec pro 28 after it seized but after repressurizing the system I now have no water coming from the hot water taps - all but a trickle which stops after a couple of seconds.
