It was not difficult. There was a good deal of satisfaction attributable to repairing a well built machine after looking over the junk that is being sold new. New machines comply with EPA rules for water conservation, etc but I've never spoken with a repairman that liked them. The most challenging part was removing old fasteners that haven't been touched in many, many years. No wonder Maytag's commercials used to talk about lonely repairmen. It turned out to be a fun project and Appliance Parts Pros helped with parts and videos. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
