Worcester 24i DHW problem

Might be a circulation problem to cause over heat. Check the pump.

McCombi · 10 Sep 2016

manual says temp sensors should be between 690 ohms and 33k ohms.

Pump doesn't run for hot water demand mode on these.

You spot on!

Hi group, quick update. Looked at boiler last night, removed cover & loosened lower panel containing the PCB & controls, fault persisted, I then noticed that if I went to close the hinged panel, the boiler would fire up so I removed the metal plate over the PCB and inspected, found what I thought was a loose wire & re-secured, put boiler back together. Tested, fault persisted, however I noticed that if I gently pushed the centre of the plastic control panel, the boiler would fire & stay on indefinitely whilst pressure was applied. Didn't have time to investigate further as it was getting late & dark. Just an update to put you guys in the picture, any further advice really appreciated.
Kindest regards Otto

This previous post may help if it's the relay issue

Yes, as above, it'll probably be the relay on the PCB. I had exactly the same symptoms and pushing the control panel in would make it work.

only couple of quid for relay or £180 for PCB

Thank you so much for all the advice guys, Relay ordered from CPC, will update once installed

Relay was fitted, boiler has been fine since August 2016, have a problem with the shower now but that's a different thread, thanks for all your help guys, much appreciated.
