Dishwasher Not Draining — West Hollywood Repair
Standing water in a dishwasher is the single most common dishwasher complaint. Most of the time it's a clog, not a broken part — but because the symptom is identical whether it's the filter, the drain hose, or the pump, the diagnosis needs to be done in order.
What this symptom usually means
Standing water in a dishwasher is the single most common dishwasher complaint. Most of the time it's a clog, not a broken part — but because the symptom is identical whether it's the filter, the drain hose, or the pump, the diagnosis needs to be done in order. Below is a breakdown of the most common causes we find on this exact problem, roughly in order of frequency.
Common causes, in order of likelihood
Blocked filter basket
The screen at the bottom of the tub catches food. When it clogs, water can't drain past it. On many modern units, it's user-cleanable.
Plugged disposal knockout
Newly installed disposals ship with a plastic plug that blocks the dishwasher drain inlet. If this wasn't removed, the dishwasher has never truly drained.
Clogged or kinked drain hose
Sharp bends or food debris inside the hose prevent drainage.
Failed drain pump
If the pump hums but water doesn't move, the pump impeller is usually seized or broken.
Check valve stuck
The valve that prevents backflow can stick open or closed. Either way, drainage is affected.
When it's time to call
Call when you've cleaned the filter and run a drain cycle and the water is still sitting. We clear what's clogged, and if it's pump failure we have the replacement on our trucks.

Frequently asked questions
Can I just run a drain cycle?
If it works, you've confirmed the pump is fine and the blockage is intermittent. But most of the time it returns.
What about vinegar and baking soda?
Those don't clear a physical clog. They're fine for deodorizing, not for drainage.
How much does this repair cost?
Clog clearing is often under $200. Pump replacement is higher — we quote before any part goes in.
