Can some one please help,
i have a valliant combi boiler and the hot water is not working properly, the heating is working fine but when i turn a hot water tap on the boiler lights for about 10 seconds then it turns off it lights again for another 10 seconds then turns off again, this repeats until you turn off the hot water tap, the water gets barely warm then goes cold then barely warm again then cold again. please can someone tell me whats wrong ? it seems like something is stuck.
thanks in advance
