Hot water is not getting hot enough.
Problem started 2 months ago when first thing in the morning it was cold then started to get hot then cold again. ( Boiler was switching on and off )
Usually after leaving it for 30 mins it seemed to be ok. Then it seemed to just get warm instead of hot. Have changed all 3 ntc`s last week but this has made no difference. Central heating is working ok.
Fault code showed F11 before replacing all NTC`S but now it shows F64.
Water is warm although temp gauge on boiler reads 72 degrees
