Hi, I’m seeking some advice on a problem that’s occurred with my Potterton Promax 12 SL boiler, the problem is intermittent. It comes on in the morning for a few hours. Then when it’s up to temperature it goes off & won’t come back on till the next day. It doesn’t come on in the evening or for a second time in the same day. Even when I try to manually or advance the central heating boiler through the Siemens RWB29 wall controller or wall thermostat it doesn’t fire up. It shows no lights on the boiler or allows me reset it. I appreciate any advice to resolve this problem.
many thanks
Richy
