GEM combi boiler overheat reset

[hughey]

Does anyone know how I can reset the overheat reset switch on a GEM combi boiler. They were manufactured in Korea and sold by the Combi Boiler Co Ltd who have gone bust so can't get manual. Cheers for any advice.

Overheat reset button is on underside of boiler to the right. Just press the button in until it clicks.

If the boiler has overheated then its necessary to discover the cause of the overheat situation and deal with the problem.

Thankyou Chrishutt. I looked all over for that switch yesterday. It looked like a screw but the advice was spot on. The pressure is always high as well and I can't seem to get that down to the advisable No. 1 on gauge.
Cheers, Hughey

After finding the reason for the overheat you should check your filling loop is not letting by.

You can lower the pressure to 1.5 bar using a radiator bleed screw into a jug or towel.

Hi Tony, I had a loft conversion done last March and thats when the pressure went up. The overflow pipe also leaks a little outside. My daughter and spouse had the heating for taps and central heating on the highest level. It was like the Sahara Desert when I come home from work two hours after the combi stopped. Could this have been the reason. I think I will have a plumber come to give it all a good check before the winter and then perhaps start saving for a new one. I use £300 quarter for gas in the winter. I pay dd £50 month and they are asking me to up it. I have five rads downstairs, four on the second level and then one in the loft conversion. Four of them are quite large.
