Standing Water Right After a Remodel: What Was Missed?

Short answer

Usually the new plumbing rather than the machine. After a remodel the common misses are a disposer knockout left in, a drain hose folded when the unit was pushed home, a loop that was never fastened, or a second check valve added to the line. Viking Repair Bothell rules each one out before judging the pump; call (206) 202-2799.

Water path through a built-in dishwasher (side section) Water gathers in the sump. The circulation pump drives it up to the lower and upper spray arms; the drain pump pushes it out through a check valve and up a drain hose that loops high under the counter before dropping to the sink drain. The door hangs on a pivot at its foot, held by a spring. 1 2 3

The route water takes out of the tub: sump, drain pump, check valve, then up the hose and down to the sink drain or the disposer inlet.

A new disposer arrives sealed

The dishwasher inlet on a new disposer comes blanked off. Left in, the blank gives the water nowhere to go from the first cycle.

Limits a new sink base can break

On the DFUD042 no part of the hose may sit above 35 inches from the floor, the run is 10 feet at most, and no extra check valve is allowed. The VDWU524 caps total hose length at 157 1/2 inches. A moved sink can break any of these.

What you can safely look at

Rinse the filters as your use and care guide shows, run the tap and disposer briefly, and look under the sink for a pinched hose. Take nothing apart. A hum with no draining points at the drain pump.

Tell your contractor

  • Knock out the disposer's dishwasher inlet before the hose is clamped on, and note it on the job sheet.
  • Slide the unit back slowly while someone watches the hose; a fold behind the tub disappears from view once the toe kick is refitted.

When to call

Call when water still sits over the filter after the checks above, when the tub empties only partway, or when a cycle halts with water inside.
