How to Troubleshoot & Replace Whirlpool AP6997612 / 4386996A Dishwasher Impeller & Seal Kit

Ordered the replacement pump seal kit from AppliancePartsPros. I watched the online how-to video on their website. The impeller was slightly stuck on the motor shaft due to age but overall was amazed at how easy it was to repair. Thanks AplianePartsPros! 

I replaced the Impeller seal kit. 

Replaced the seal along with the impeller seal kit, it went very well thanx to your very helpful video and timely service 

With the exception of the chalk outline my wife drew on the floor indicating where the water was coming from, my experience was nearly identical to the other folks who commented on this repair. The most difficult part was unscrewing the plastic retainer above the impeller. Years of soap and or calcium deposits seemed to lock it in place. It eventually broke loose after applying slow steady pressure to the vanes in the plastic piece. The old impeller was another challenge. Had to destroy it to get it out as it was seized on the motor shaft. Note: if you need to do the same, be sure to vacuum any debris from the housing. Don't want anything to ruin the new seals! Realistically it took about an hour and a half to diagnose the problem, watch the excellent video, disassemble the pump and order the parts. Parts were ordered on a Saturday, arrived on Tuesday.Within a half hour everything was back together and working fine. (for a 20+ year old Dishwasher)

After researcching the problem and watching the repair video, I ordered the parts from AppliancePartsPros on a Monday and had them delivered to my door on Tuesday via standard shipping (exceeding my expectations and beating your average time by a day)! Had some difficulty removing the original impeller (the dishwasher is 19 years old). But after breaking it apart and shaving off the old one with a chisel had it back together in under an hour. Works great and no more leaks. Thanks for the super quick service and the repair videos. John - St Louis, MO 

The video that was underneath the impeller/seal kit that I ordered showed exactly what I needed to do. Note: if you find a spring under the impeller during disassembly do not put it back in with the new kit parts. That old spring came from inside the old impeller seal. The new part has the same spring already inside of it. Also, the video doesn't show it, but you need to disconnect the drain hose from the attachment under your sink, next to your faucet, in order to pull the dishwasher out. 

New impeller - the kit comes with the impeller and two gaskets needed to water seal it (but the description says it only has the impeller). Had to use dikes to cut the impeller in pieces to get it off as it was fuses to the moter. 

I ordered a new impeller kit from you. It arrived quickly. Thank you.
