Aqualink RS4 dead?

[scimini]

I went out this morning to empty the baskets and noticed the water was still. Checked the pump and wasn’t running. Checked breakers all good. Opened up the box and there are no lights illuminated on the aqualink. Flipped all breakers. Everything came back but the aqua link.

Is there anything I can do/check before calling it doa in under two years.

Welcome to TFP.

Lots you can check if you have a multimeter and know how to use it.

Start with the transformer and see if you have 120V/240V into the transformer and 24V out.

Check you have 24V AC at the PCB,


I think there is a fuse on the PCB near the 24V connector.

Thank you so much! Using the multimeter I was able to see I was missing one half of the feed. Backtracked to a gfci outlet that I don’t use but was inline. It was tripped. Once reset I was back up and running.

At least I know that outlet is inline from now on and have another checkpoint
