Hello! Can anyone help me please with a Vaillant 242/1E, I have heating but no hot water, the led lights are working, except the hot water one. Thanks in advance!
check diverter valve operation.
locate this switch on the right hand side of the diverter valve. as you open tap, a plastic lever will push down on the switch. if it doesnt the valve or its diaphragm is faulty. You can try pushing the switch manually while the tap is on to check it will fire up ok. View media item 11732
