I'm having problems with the DHW supply from this boiler. Water doesn't reach more than luke warm temperature. Slightly better after reducing water flow but that makes showering difficult. I've replaced the DHW thermistor but there has been no improvement - in fact it's worse as the boiler now cycles on and off every couple of minutes. CH appears to be working fine.
its your primary side / CH thermistor right hnad side lower of boiler item34 on manual e23-715 mine goes every two years like that. New thermistor and ok again. only cost about 20quid.
