BigChiefNocaHoma, an Apprentice Appliantologist at the Samurai Appliance Repair Forums, owns a Bosch front washer, model number WFMC3301UC. Recently, his Bosch washer developed a problem where it would stop mid-cycle with an E04 error code in the display and he posted this problem in the Laundry Appliance Repair Forum. Sublime Master appl.tech.29501 talked him through it by leading him to check the pump for gookus (that’s a technical term that refers to anything what ain’t s’posed to be there; please, I *am* and professional, don’t use this word at home). Anyway, the stunningly simple solution and an illustrative page from the service manual are all posted in this topic at the repair forum.
