I had replaced the drain pump 8 months ago. I read 14 ohms across the pump and the wiring to the control board. The impeller felt fine with no wobble or play detected, free turning.
Unlike the first time the controls at any position, lights a light at another. Only F-33 shows up and no other faults. So, will the original fault clear only to show current fault? I'm unable to do any further diagnostic test. The door will relock and dial light jumps to only
two functions. So, I feel that I may be getting blindsided by a second fault, and possible mainboard issues. Thanks in advance!

F-33--->PUMP DRIVE SYSTEM ERROR
Possible Causes/Procedure
1. Unplug washer or disconnect power.
2. Check wire harness connections to the pump and Central Control Unit (CCU).
3. Plug in washer or reconnect power.
4. Verify CCU operation by running a Diagnostic Test or any cycle. Refer to the Continuity tests on page 10.

Only F-33 shows up and no other faults. So, will the original fault clear only to show current fault?

The tech. data sheet does not mention that. I'm attaching your tech. data sheet below, you can see for yourself.

That drain pump should be at 12.3 ohms, 14 ohms is too high. Did you buy the drain pump at AppliancePartsPros and RepairClinic because they always have a 365 day warranty on ALL parts.

Here's the drain pump for your model:

Also try this--->Starting Diagnostic Test and bypassing the Service History Mode:
Execute this procedure with an empty drum. All of the steps below must be done in sequence in order to reach the Diagnostic Test. This executes the automatic test but does not show the error history.
■ Close the door.
■ Push POWER.
■ Select the CLEAN WASHER cycle.
■ Press EXTRA RINSE four times within 5 seconds.
■ Press EXTRA RINSE to advance to the next step of the test procedure.
■ If the starting procedure fails, push PAUSE/CANCEL, then repeat the starting procedure.

Thanks Jake

No, pump was from amazon. Hail Mary replacement due tomorrow...will check new coil reading when received. Odd, I have never seen a coil gain DC resistance other than corrosion. If we had a way to clear old errors, I would tend to trust the codes further. I did read the pump directly and from the disconnected connector from the controller board, both connectors on tight. If new pump show the approximate 12.3 ohms, I'm sending it back to try your suggested pump.
I am unable to start diagnostic tests after several tries yesterday. Only finding the old error code works reliably. As before when dial set to one wash function, another light would come on at another function.

Then it's possibly the CCU:

That $285 board shows out of stock. Lol, no wonder, washer serial date code shows U for 2008? Whirlpool has a new one that cost TWICE as much as the one shown. Anyway second, same, replacement pump arrived reading 13.9 ohms with cpu still showing old F-33. And, still won't start.

Main drive motor reads 6 ohms across phases, both water valves read the same to each other. There was not an error code for cpu or motor controller, that would be too easy? Machine is clean but also needs new shocks and front bellows just starting to weep on bottom front edge.

Wife wants to go find new matching set! Stubborn self wants to find used cheap CPU card just to see...

Thanks for your help but I'm now being ordered to cut and run!

That still seems too high,

This guy here was getting 11.8 and 12 ohms at the drain pump terminals:

I have a Whirlpool washer, model wfw9150ww00. At first the problem was intermittent - it would stop midcycle, not drain, with 3 rapid chirps. The door stayed locked. I was able to reset it and get it working again by flipping the breaker. That no longer works now. I have run the diagnostic...
