Question about Whirlpool GU2400XTP Built-in Dishwasher
The 2400XTPT cycles properly and works normally until the drain cycle starts. When draining first starts there is little noise but as the water is emptied from the unit the sound becomes unusual from that of when it was first installed. It only makes the sound when draining. The sound is not so much a grinding as it is the sound of a defective impeller or bad bearing. With the kick panel off I can reach and feel the drain pump and feel vibrations matching the sound. I highly suspect something is wrong with the drain pump. How difficult is it to replace the drain pump on this unit? And do you agree with my idea as to what the problem may be? There appears to be an electrical lead to this drain pump. Just wondered if the lead could be pulled during this noise to see if it is indeed the drain pump. What I really need is a master repair manual for this particular Whirlpool dishwasher.

Yes, you can pull one of the pump's leads to find whether the noise comes from the pump. You should unplug machine's power cable first and be sure that the disconnected wire is isolated. Before replacing the pump look that it clean from any foreign object/ Good luck!

Tips for a great answer:
If suds are detected continuously by the pressure switch during the drain or spin phases, the washer will fill 4 liters of water and during 5 minutes the unit will rest without tumbling, the water will be drained and it will try to spin or drain again.
• If too much detergent was used:
- Run the unit through a RINSE/SPIN cycle.
- Run a NORMAL cycle without adding any detergent,
• This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged or kinked.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the drain pump, pressure switch, and Central Control Unit (CCU).
4. Check/clean drain pump filter of foreign objects.
5. Plug in washer or reconnect power.
6. Check drain pump.
7. Check the pressure switch.
8. Verify CCU operation by running a Diagnostic Test or any cycle.
