My toilet pump pcb appears to be at fault  pump not operating

I have checked the Fuse ---OK

I have checked  the input to the pcb under the push button and have 13 v  --- OK

I have seperately tested the pump with separate 12 v supply    Running OK

Cannot get a voltage reading at the PCB output to pump .

I have Changed the PCB but get the same results.

Any suggestions to where to test .

Many thanks for reading

    Have you tried drying the PCB, using a hair drier, as condensation was causing ours not to function, and a quick warm air dry off proved the solution to get it operational again?

    Thank you Nelliethehooker for your suggestion.

    I did try this but with no success.

    I have now disconnected the +- for the pump at the pcb and connected a +-  thro.   a rocker  switch direct to the pump .  I have left the supply +- to the pcb and this still enables the red warning light to work as normal.     I have refitted  the Thetford  sticker over the rocker switch so the finish is just the same.

    I did  appreciate  your reply
