Hi
Can anyone help?
Friend of a friend asked me to help her old grandmother who cant afford to get Alpha or BG out.
I dont have any experience of Alpha range at all, only qualified last year!
The boiler has no fault indicator flashing its on standby, (B flashing every secs)
On demand for DHW only o CH as well the pump operates but the boiler does not fire up
I replaced the diverter valve and flow switch as the flow switch fell apart when i took out and the diverter valve was so corroded.
Did a resistance test on the Primary temp sensor and DHW temp sensor both within range when cold although when measuring on the PCB with pump running
reading -161.9 om ^ is this normal?
Any ideas?
