I replaced the circulation motor and heater assembly. The video tutorial was helpful as far as location and connections of the assembly, but the demo dishwasher unit was open on the bottom, so access was unencumbered once the unit is pulled out and laid over on its side. My model is mounted on a plastic skid, which completely eliminates access from the bottom. Rather than spend time removing and replacing the skid, I pulled insulation away from the sides of the unit and was able to remove and replace the pump assembly by working through the sides of the unit. Note: working through the access areas on the sides is one hand only. I removed the clamp using a diagonal cutter through the left side of the unit. I removed electrical connectors, then removed the pump through the right side. I positioned the new clamp on the hose through the left side - just snug enough that it would hold its position, then installed the new pump assembly through the right side. Final clamp tightening was done through the left side. The total job time was approximately 75 minutes. FedEx delivered the part less than 24 hours after I ordered it!
