Hello, hoping someone might be able to shed some light on our issue. I have a Combi Boiler - Worcester Highflow 400 electric - 2004 model.
We had a central heating leak, was losing 1.5 bar within 20mins. I located the leak under our solid oak wooden flooring, turned out to be a copper pipe with no lagging rubbing against a brick and had worn a hole.
I have replaced the pipework in this area by using 15mm couplers and re-soldering a section back into the two CH pipes which were laying across the brickwork.
Following the work, the system was re-pressurised and boiler power turned back on at the wall. I opened all of the valves on the radiators and bled the air out of each radiator whilst re-topping up the system pressure. The system is holding pressure (well has done in the past 5 hours) so I am assuming that the original issue is now fixed, but the CH system is not turning on when I start it?
If I turn the boiler off at the wall and then back on, both CH and Hot Water lights turn on red for about 3-5 seconds, then dissapear.
The hot water system is working ok, and the light comes on red when in use and boilder fires up. The CH system however, is showing no lights and the boiler does not even try to fire up when the CH system is turned on.
Is there a reset button you have to active after re-pressurising a system with this boiler?
One thing I notice is that the CH dial on the boiler (the temperature setting dial) spins around and around with no friction or end point, but the hot water one has an end point when you turn it anti-clockwise. Is this usual?
Thank you for any thoughts around this issue.
