The part that I ordered is exactly what I needed. It got here in a very timely manner in excellent condition. The delivery driver was a very pleasant individual. I will explore Walmart in the future for any additional appliance parts that I may need. The price is very competitive and the delivery time is outstanding. Thank You Walmart, Phil

Buy this before buying a new heating element!

This is an OEM part from GE so it fit and worked perfectly. I bought one from Amazon and it did NOT seat properly on the connector. The dishwasher would not fill with water. I bought this, received it in 2 days and installed it in less than 10 minutes. Hot water again and fixed my dishwasher for less than $30. Easy fix!

Best place to buy. Genuine GE OEM part

Best price anywhere and in stock. Fast ship, arrived exactly as advertised; a genuine GE OEM part. Don't pay a plumber when your GE dishwasher stops heating the water and drying the dishes. Replace this part in less than 20 minutes with only a screwdriver.
