You have 3-port from what you describe. Can you please check on your hot water or heating demand, there is a small lever on the zone valve is this moving freely.
Call some one who knows open Vented system, it usually comes down to poor system design, when the water starts to overflow.
If you can combine the feed and vent in the loft by expansion tank to start with and see if itstill is over flowing.
I had my colour vision test and unfortunately I didn't get in. The test is on a board with various colour combination of wires on connectors and given 20 questions to answer them all correct and I got 3 incorrect, it had to be 100%. Gutted but not given up.
I wonder if any one can help. I have had my interview and being color blind didn't help. So I have been asked to come to there training academy coming Monday and do a Trade Test.
Does any one has any idea what a Trade Test involves.
Any help much Appreciated
Been to the above boiler today. The PCB was replaced a year ago. The boiler goes into lock out mode after every 5 - 10 minutes, after resetting it fires up nicely. But again locks out. Do I need to change the overheat thermostat and temperature sensor or is it some thing else.
I have had to deal with this boiler twice and in both case ended up stripping the boiler and cleaning each bit on it. The sludge sticks to every part on it.
Vaillant 824e Turbomax Plus comes up with fault code F28. Did all my resistance and voltage check and still nothing happening. It goes all the way to ignition but does not fire. Hence decided will go next day with a new gas valve, turned up next day without one just wanted to check what could be...
I did change the boiler , but was curious why was C25 not firing, so I decided to strip the boiler in me garage and found that the burner had broken and lying on the heat ex changer.
Hello All
Just stuck on a C25 keston , wondered if any of you have come across the problem. The boiler seems to be doing everything except firing. It goes all the way to ignition and gas valve opens up as I can smell it but its not firing. What am I missing. Help much appreciated.
