Sorry could not find any info on this Model Number so am guessing
Also is your solenoid reading 0.81 ohms seems very low
Are you sure it is not 0.81 kilohms
I would double check the float switch itself, the float sometimes leaks, it runs down onto the switch and solidifies into lime deposits on the switch's button
Please remember this is a guess
I cannot see it being any thing but the solenoid or the timer
Since it is intermittent, it is a pain
Personally I would replace the inlet valve first
And if that does not fix it then the timer
But I am basically cheap and patient when it comes to fixing stuff |
