Use CLR in the soap bin, degreaser in the bleach bin, and white vinegar in the softener bin. Run the system clean cycle. If you continue to have errors repeat the clean process. Be patient it should work. Repeat the clean method every two weeks, reduce load size, add only 2 TBS soap (or replace tumble chamber area with 1 cup of Borax. If it works once after giving it a night's rest, then you know it is the full syst clean that is needed. No extra parts. One last try is to blow very hard multiple times in the black rubber sensor tube very hard after a wash cycle.

Prior to any parts replacement. 1. Fill each cavity of the dispenser with a high strength degreaser. 2. Run system clean. Setting is at 6 O'clock position. Repeat with CLR cleaner. 3.

I am happy to say I have run 20 loads of various types without any error codes. The repeat maintenance I performed was the CLR decalcification clean under the system clean cycle of hot water cycle (such as towels). When the error E03 occurred I: Vacuumed the drain port while the pump was draining. Repeated until door lock opened. Placed CLR in all the dispenser trays (total) 1/8 cup. Added 1/4 cup of baking soda to the bin Ran a hot cycle or the system clean cycle On the next load I added only 1/2 the normal amount of clothes for 4 load cycles. Used 2 Table Spoons of Tide HE laundry detergent and 2 Tables Spoons of Softener. Ran hot water cycles Repeated the cleaning cycle with CLR after each cycle. Now the E03 error is gone and the washer runs consistently. I believe this cleaning method is a first diagnostic approach to help isolate any other issues. It can save on any physical repair or call to a tech.

I have a Whirlpool front load washer with the FO1 and EO3 error. This indicates that water is detected by the pressure sensor water level circuit. I realise some patients is needed in my analysis. I hope it helps you address the issue with some valuable insight. Make some observations. You may smell the inside of the washer. Does it smell damp with sour soap washer residue ? Consider that there is a buildup of scum throughout the washer. Disconnect the power and remove the rubber connector from the drain port of the machine at the top left. Attach a shop vacuum hose so that it fits over the drain port to remove the residual water and potential build up. reattach the drain hose. Add two table spoons of a water based degreaser such as Zep Orange Citrus to the bleach section. Add vinegar to the rinse softener section. Add 3 table spoons of CLR to the detergent section. Add 4 table spoons of baking soda to the tumbler. The degreaser, vinegar, and CLR will clean the dispenser and enter through the water inlet...
