I have a top load washer with the Kirkland name on it, but I'm pretty sure it's made by Whirlpool.

A few weeks ago it stopped at the "rinse" cycle, tub full and wouldn't go any farther - not even manually moving to a later part of the cycle, or in a different wash type. It wouldn't drain on any setting. I checked out many repair videos and started with the lid switch, which is good (tested with ohm meter). I took off the water pump and motor and the coupler is good and the pump was clear of debris and spun with a good amount of friction (I assumed this was just the seals). I ordered a used timer found on Amazon, installed it and it worked again for a couple of weeks (probably a half dozen loads). Is it likely that the second timer went bad in the same way without anything else being wrong? Is it likely that there's some other problem that's causing the timer to malfunction. Is it even the timer? The timer does make a very faint clicking/humming in some positions as if something is trying to happen.

It's definitely not the lid switch. I'm happy to buy a timer from you as long as it's not likely that there's a secondary problem that's causing the timer to go bad.

Two other pieces of information. One is that the agitator works fine so it seems like the motor is good. I popped the old timer apart (it's not designed to come apart but I figured it wasn't working anyway) and one of the reed switches inside is very burnt from arcing. This makes it seem to me like it's pulling too much current, but is that normal?

Here are two photos. I'm not seeing the model number anywhere obvious.
