KitchenAid KDTS424S Dishwasher Repair

KitchenAid dishwasher

Most common issues on this model

  1. Drain hose clip worn, so the joint weeps only while the pump runs
  2. Mineral scale coating the heater in hard-water kitchens
  3. Diverter that sticks, sending water to one rack only
  4. Pump that hums at drain time but leaves water behind

A KDTS424S is still a current KitchenAid dishwasher, so the ones we see are usually young enough that repair is clearly the better route. When one does call us early, the cause is often a mineral film on the heater and spray system in a home with hard water.

On arrival we run a cycle and watch it rather than guess. The drain hose and its clip come first, since a leak that shows only while the pump runs points straight at that joint. After that we look at the sump, the spray arms and the diverter. Units marked KDTS424SPS are the same base model and get the same checks.

You receive a written price before we touch anything, and the work carries our 30-day workmanship warranty.

KDTS424SKDTS424S questions
Why does my KDTS424S leave water on the floor only during the drain stage?

That pattern usually means the drain hose or its clip has worn at the connection, so water escapes only while the pump pushes. We trace the hose from the pump to the disposal or air gap and replace the worn clip or hose section.

Is the white film on glasses from a KDTS424S a sign of a failing heater?

Not necessarily. Scale on the heater and in the spray system causes dull glassware and slow drying in hard-water kitchens. We inspect the heater surface and spray jets, descale where needed, and tell you before any part is replaced.

The upper rack of my KDTS424SPS stays dirty while the lower rack is clean. What do you check?

We check the diverter and the wash-arm feed first, because a feed problem sends water to one rack only. We also clear the spray jets and confirm the pump pressure is reaching the upper arm.
