Question about Kenmore Elite 45986 Front Load Washer
I suspected suds build up, so I tried both regular wash cycles (e.g. Normal) and Rinse and Drain cycles multiple times to clear suds in the system, but still received the F02 error. Sometimes the SUD error message came up, but not consistently.
I ran the built-in Diagnostics tests. It made it to C:06 then got stuck.
In both scenarios above, the washing machine continued to try to pump water out, despite the fact that all the water had already been drained. After 8 or so minutes, the F02 error came on. As I understand it, if the pressure switch detects either water or suds, it commands the drain pump to continue. After 8 or so minutes, if it's still detecting water or suds, the F02 error is displayed.
I performed the following with no success:
1. Check Wire Harness connections - OK
2. Check Drain pump. – OK, as water drains at a rapid rate
3. Check Drain pump motor - OK, as water drains at a rapid rate
4. Check that the Drain hose and Drain Pump Filter is clear of
foreign objects. – OK, ran a cable through both hose assemblies (exterior and interior) and not blocked.
5. Check the CCU – appears to function normally.
6. There were no kinks in the hoses, nor was the height of the pump beyond what the manual recommends.
After more diagnostics and troubleshooting, I found that the Pressure Switch was stuck and reported the SUDS state (continuity made between contacts 11 and 14 on the Pressure Switch itself). I ran many Rinse and Normal cycles with no detergent and still got this F02 error. I checked the state of the Pressure Switch’s Empty and Level 1 contacts which intermittently reported the correct water level condition (EMPTY and Level 1). In all cases contacts 11 and 14 (SUDS) were continuously made (connected) irrespective of water level, rinse conditions and the use of no detergent.
I removed the pressure switch and tested it by blowing into the inlet and did hear the switch click, so it seemed to work properly. Given the diagnostics above, I concluded that the pressure switch hose must have been clogged.
Good Luck!! Thanks for using FixYa!!
