You cannot do much checking in a boiler without a multimeter!

Resistance of sensors?

"ON" resistance of microswitches?

ok found it m8 pcb board gone totally burnt out at plug to microswitch only??
must been a short somewhere , will try to source a new board , how much would this cost ?

 

[Agile]

About £100-£150 ?

Could you have shorted a microswitch connector to chassis?

OP There is 240 volts on the wire. Do NOT attempt to short cicruit or touch the wires on the microswitch. 240 volts live supply caution to be observed here.

If the pump not running, then follow the manual flow diagram if REALLY must go there
