My Whirlpool dishwasher (described above) has just started to act up. I first noticed that after running the dishwasher, the dishes did not appear to have been cleaned.

Upon further investigation, I am seeing the dishwasher fills with water, then the pump starts VERY BRIEFLY before stopping and draining the water. These steps are then repeated. Water is not being pumped to either the lower or upper spin arms.

I disconnected the upper spin arms - still has the problem. I disconnected the lower spin arm, too - still has the problem. When I remove the plastic impeller piece, however, the dishwasher appears to run normally (however I am not cleaning my dishes).

From some online research, it appears that it may be related to the Soil Sensor? Is there any way that I can 'reset' or 'adjust' the sensor? Perhaps it is the small tube to the sensor being clogged? (can someone tell me where I can find that tube)

Any help would be appreciated! I'd like any suggestions where I can address this myself, if possible, before calling in the professionals.

Thanks!

Thanks Denman - sorry for the long response time...finally had some free time to work on the dishwasher. Indeed I've discovered that disconnecting the pressure switch has allowed the wash cycle to run 'normal'.

I'll look to either clean out that little hose or replace the pressure switch...

However now I'm experiencing a new problem. When the dishwasher is running, it seems that I'm no longer getting a good seal between the pump and the lower wash arm. (Some water will come out of the holes, but not at enough pressure to spin the rinse arm.) Also, there is not enough pressure being generated to pump water up to the upper rinse arm.

On the 'Lower Dishrack Parts' diagram, it just doesn't seem like I'm getting a tight enough seal with parts #10-13. Any ideas?
