Old maytag washer LAT9704AAE not draining and spinning - not clogged just stumped

[cristo774]

My old maytag washer - dependable care plus - circa 1999 - LAT9704AAE was working great until I washed a cat bed @ a week ago and it came apart and clogged the drain pump :(

What it is doing: It will fill and agitate properly, but when it gets to the drain and spin part, it will go for @ 3 - 4 seconds, I hear a click and the motor turns off.

The timer will keep going although the machine is doing nothing until it gets to the second drain and spin part and repeats; 3 - 4 seconds and the motor clicks off.

So essentially it won't drain or spin with water in the tub.

Obviously it won't drain if the motor is not turning the drain pump. It will go through a whole spin cycle fine with no water in the tub? So the timer doesn't seem like the problem. Motor and transmission seem to work fine. The pressure switch fills water to the proper level. Why would the timer be clicking off the motor? I don't see how a clogged drain pump could have ruined the timer?

I'm guessing the timer is "sensing" some kind of electrical overload situation and clicking off the motor? I know there is only one sensor on this old machine ( air pressure sensor ) and one fuse on the lid switch assembly. What would be causing an electrical overload? Could it be the pressure sensor?

Things I have done so far:

replaced the drain pump ( but that didn't seem like the problem once unclogged )

replaced the belts

replaced the lid switch assembly

cleared all the hoses and outer tub of debris ( took the inner tub out )

tested the motor and transmission with a bypass cable ( both work fine )

Stumped :(

I like this old machine. It worked good and fast compared to newer models; and was in good shape until the clog. There has to be something I can do to save it without paying for parts that cost more than I paid for this used beauty.

"Aftermarket belts generally don't play nice as they're not engineered for proper slipping during the initial spin cycle phase. Aftermarket belts generally grip instead of slip, causing the motor protection circuit to kick in and out. Use genuine Whirlpool/Maytag belts ONLY"

It was the belts. With the new belts from amazon on, the machine was pulling 20 amps! and obviously tripping the motor protection circuit. With the old belts on, the machine is pulling 6.8 amps and working fine now.

What a relief. I was ready to spend $ on expensive parts that I didn't need. I guess all I needed was a bit more knowledge

Thought I should add that the new belts are the right part numbers and only seemed a little tighter than the old belts.  But I guess it made a BIG difference.
