Buzzing sound from pump delay timer PCB
An intermittent buzzing sound comes from the pump delay timer PCB. It only lasts about 2-3 seconds and seems to happen when nothing else is happening eg primary pump not activated.
I recently replaced the PCB in an attempt to stop the buzzing but it has made no difference. I have assumed that the replacement PCB is defective and will try a second replacement.
Is anybody aware of another possible cause?

Thank you. Unfortunately Fig 18 does not help me much. I noticed you assistance to EW and have posted a question to him. It appears that his "buzzing" was cured by replacing the pump drice PCB. Please comment on my question to EW.
Have a good Christmas.
