Hello all,
Yesterday, our washer (Maytag 2000 Series) started reporting an "LF" error.
The service manual tells me that it is a "No water detected entering wash or pressure switch trip not detected".
I have read through the Possible Causes / Procedure section.
What I’ve done so far to diagnose / troubleshoot:
- Checked to make sure water was turned on for both hot and cold (yes).
- Checked water pressure for both hot and cold (normal pressure for both).
- Checked the filters for both the single (hot) and double (cold) inlet valves (clear).
- Checked the hoses from the wall to the washer and the inlet valves to the detergent compartment for kinks or leaks (none).
- Checked the inlet valves for resistance using my voltmeter (both passed).
- Checked the continuity of the pressure switch (passed).
- Cleared the error and ran the diagnostic test per the service manual (all passed).
Now…here’s where it gets interesting:
When I attempt to run a load of laundry (in this example, it was on Normal cycle, Cold, Extra High Spin, Normal soil level), the water does begin to fill the tub, but in a noticeably lower pressure/speed than when I run the diagnostic test or when I do a "Rinse/Drain/Spin" cycle. When I run the diagnostic test, you can very clearly tell that the water is coming into the tub at a much faster rate.
Following running the above load of laundry and getting the LF error, I changed to "Rinse / Drain / Spin" mode and started the washer again. Very noticeable change in the speed of the water coming into the tub.
Does anyone have any thoughts as to what would cause this? I am assuming that the inlet valves are either open or closed, with no in between. The water (hot or cold) valve opens, water enters the tub to the pre-determined level, then is shut off via the pressure switch activation.
It doesn’t make sense that there would be such a dramatic difference in the speed of the water entering the tub.
Any comments or suggestions are very much-appreciated.
