Standing Water After Every Cycle
| Reading | Likely cause | Owner check | Price band |
|---|---|---|---|
| Water across the tub floor, food packed on the filters | Filters matted over, so the last of the wash water cannot reach the pump | Power off, twist the filter set out, brush every piece under the tap | Quoted after the diagnosis |
| Began after a new disposer or plumbing work under the sink | Disposer inlet never opened, or the drain hose flattened or sagging low | Run the disposer; look along the visible hose for a fold or a dip | Quoted after the diagnosis |
| Filters clean, a hum when it should empty, level unchanged | Drain pump jammed by something hard, or worn out | Nothing past the filters; breaker off, and leave it for the visit | $190–$380Dishwasher pump or control |
The cycle ends with water sitting in the bottom. Usually a clogged filter or drain hose; after that the drain pump.
Start at the filters, end at the pump
Start at the filters. Row one covers most standing water and needs no part. Recent Viking dishwashers catch food in a set of three filters set into the floor of the tub; once rice, seeds and grease mat them over, the tail of the wash water cannot get down and out. The current manual asks for a clean at least once a week.
Row two is where Tacoma’s remodels come in. Around the North End and Proctor, many kitchens have been redone inside far older houses, and a new disposer often goes in with the new sink. One whose dishwasher inlet was never opened gives the water no way out; Viking’s installation guide has the installer clear that connection before the hose is fitted. The hose counts too. Viking wants it raised in a loop no lower than 28 inches off the cabinet floor, and warns that without it the machine drains poorly and starts to smell.
Row three is the pump. A hum when the tub should be emptying, with the level going nowhere, is the drain pump asked to run and moving nothing. A hard scrap can stop it; age can too. Only this row lands in the pump-or-control band, and only when the pump itself is replaced.
Before any of that, rule out an interrupted cycle. A recent Viking opened mid-wash stops, and left untouched for a few seconds it switches off with the water still inside.
Owner checks, in this order
- Turn off the dishwasher's breaker first. Viking's manuals ask for the power to be off whenever the machine is being cleaned.
- Roll out the lower rack. On recent Viking models the round filter turns anticlockwise and lifts; the flat screen under it slides out. Mind the sharp rim underneath.
- Brush each piece clean under running water, set the flat screen back, and turn the round filter until it clicks. Never run a cycle with one missing.
- Under the sink, see whether the drain hose climbs in a high loop before it meets the drain, and whether stored bottles are pressing on it. Note it; loosen nothing.
- Stop there. Anything past these checks means panels off or gas and wiring, and that is the $89 visit from Viking Repair Tacoma: (206) 472-1140.
Asked about this one
How much water left in the bottom is normal?
Some. A shallow pool down in the filter well is part of the design, and Viking's installation guide expects it to settle below the filter screen once the cycle is over. The fault this page deals with is water lying out across the tub floor, or water that survives a second full cycle.
Does a drain pump always have to be replaced?
No. A pump stopped by a bone or a sliver of glass can sometimes be cleared with no new part at all. One that has worn out is replaced, and that job sits in the pump-or-control band shown in the table. Viking Repair Tacoma prices it before any work starts, after the $89 visit: (206) 472-1140.
