Do-It-Yourself Stories from Customers like You Leaking hose upper spray arm and drain hose replacement   Elizabeth D. • Afton , VA • May 19, 2015

Removed dishwasher to replace spray arm pine--I replaced washer on pipe, too, and would recommend doing this just on principal. Removing dishwasher requires disconnecting power, water, and drain line--tools will vary depending on connections. i replaced drain line because original install was not done correctly--hose too short--You could probably do just this w/o pulling unit. All parts arrived very quickly and fit correctly. Read more

Water Level Switch (Float)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP99002560

This water level switch senses the dishwasher's tub float and controls the water inlet. Replacing a worn switch restores correct filling, helping prevent overfilling or dry cycles that can reduce cleaning performance. What it does:

  • Monitors the float position to open/close the fill circuit at the proper water level
  • Common symptoms: dishwasher won't fill or stops filling too soon
  • May also cause continuous filling/overfill if contacts are stuck closed
  • Intermittent operation can leave the tub underfilled and washing performance poor

What's included:

  • 1 water level (float) switch

Install notes:

  • Disconnect power and shut off the water supply before servicing
  • Remove the toe/kick panel to access the switch near the float assembly under the tub
  • Note wire positions; transfer connectors one at a time and secure the switch in its bracket
  • The float moves freely and actuates the switch before reassembly and testing

This part fixes the following symptoms
  • Will not drain
  • Won't start
  • Will not fill with water

Do-It-Yourself Stories from Customers like You Dishwasher wouldn't drain   Ken S. • Columbus , OH • August 18, 2018

I called and talked to a customer service rep and she helped me troubleshoot the problem and order the correct part. She also sent me the pdf of the repair manual and I followed its instructions to replace the drain solenoid. It was a fairly easy repair. I wasn't sure if I would need the water level control switch, but I ordered it to be on the safe side. Turns out the original is still good. Read more

Do-It-Yourself Stories from Customers like You Door kept falling down at the slightest touch   James S. • Albany , CA • July 13, 2016

These springs work great but I did find some issues when installing them. Here's what I did: 1) Turn off the power to the dishwasher at the circuit breaker or fuse panel. Once you remove the kick panel there are a lot of exposed wires that carry live power. 2) Remove the kick panel. There are 4 screws (on mine one was missing). A nut driver makes it much easier. A flat blade screwdriver can be used but it will be much more frustrating. 3) Latch the dishwasher door and remove the access covers... Read more

Do-It-Yourself Stories from Customers like You The siphon break got broken during our move   Barb H. • Castle Rock , CO • April 15, 2017

I have a Maytag washer that is over 30 years old and still runs like a top. When the siphon break got destroyed in our move, I was able to find a replacement kit that fixed our problem. I found a video on UTube that showed us just what to do. I'm delighted I didn't have to buy a new washer since the quality of new ones doesn't hold a candle to the quality of my Maytag. Read more
