The independent appliance repair shop across the Pacific Northwest
Dishes Coming Out Dirty
If your dishwasher runs but the dishes come out dirty, the trouble is almost always water temperature, spray flow, or detergent, and that's a repair we handle across Portland kitchens. Glasses feel gritty. Last night's rice is welded to the plates, coffee cups look cloudy, and yet the machine fills, drains, and latches like normal. Nothing is broken in the obvious sense. It just isn't cleaning, and that's one of the calls we get most.

What "not cleaning" is actually telling you
A dishwasher needs hot water, water moving with real force, and detergent that dissolves. Lose one of those and you get dirty dishes. The film or crust left behind tells you which one quit. Chalky white haze usually points at hard water and rinse aid. Gritty sand-like specks point at the filter or drain, while food stuck only on the top rack points at spray arm flow. Baked-on residue on everything often means the water never got hot enough. Look at your dishes before you look at the machine. The pattern narrows it down fast.
Cause family one: loading, detergent, and old habits
This is the cheapest fix, and it settles a lot of calls. Overlapping plates block spray. A big mixing bowl face-down over the center creates a shadow where nothing gets wet, and tall pot handles stop the upper spray arm from spinning. Detergent matters too. Pods stored in a damp Portland laundry room or under-sink cabinet clump up and quit dissolving, and old powder goes stale. Skip rinse aid and you get that cloudy film people mistake for a broken machine. Run one load packed loosely, with fresh detergent, rinse aid topped off, and the hot tap run at the sink first. Sometimes that's the whole repair.
Cause family two: the filter, sump, and drain
Most modern dishwashers have a removable cylinder filter down in the floor. Food sludge builds up there, and then dirty water gets sprayed back onto clean dishes. Pull the bottom rack out and twist the filter free. It's made for hand removal, no tools. Rinse it under the faucet with a soft brush, then check the shallow sump underneath for glass chips, fruit stickers, and toothpicks. Look at the air gap or the loop under your sink as well; a partly clogged drain line leaves standing water that stinks and re-soils everything. If water sits in the tub after a cycle, say so when you call. That changes what we bring.
Cause family three: spray arms and water delivery
Spin each spray arm by hand. It should turn freely. Hold one up to the light and look at the little jet holes, since mineral scale and seeds plug them and our regional water leaves deposits. Many arms unclip or unscrew by hand for a rinse. If the upper rack has a feed tube at the back, make sure it isn't cracked or knocked loose. When the arms are clean and dishes still come out dirty, it's usually pressure: a tired wash pump, a worn impeller, or a clogged inlet screen. That part is ours to test, not yours. Leave the panels on and keep your hands out from under the machine.
What we do that a home check can't
We put the machine into service mode and watch each part of the cycle in order. We measure incoming water temperature and how much water actually fills the tub, because a weak fill valve looks just like a weak pump from the outside. We test the heating element and thermistor for resistance, check the diverter valve that alternates upper and lower spray, and read stored fault codes. Then we tell you whether it's a part, a plumbing issue, or a habit worth changing. We're an independent shop and work on all major brands. Call us and describe what the dishes look like. That's genuinely useful.
Dishes Coming Out Dirty — quick answers
Should I rinse dishes before loading?
Scrape, don't rinse. Modern detergent needs some soil to work against. Do get rid of bones, corn silk, and stickers, since those are what plug filters and spray holes in the first place.
Why are my glasses cloudy instead of dirty?
That's usually mineral film rather than food. Add rinse aid, use a dishwasher cleaner made for scale, and check your water hardness. If the etching feels rough and won't come off, the glass itself may be damaged.
Does running the hot tap first really help?
Yes. It clears cooled water out of the pipe so the dishwasher's first fill comes in hot. A cold first fill means detergent doesn't dissolve well, and some cycles never fully make up the heat.
How it works
- Step 1
Tell us the symptom
Call us or fill out the form and describe what you're hearing, seeing or smelling. Brand and rough age help. We ask a few questions up front so the likely parts ride along in the van.
- Step 2
We come look
A technician shows up in the window we set, pulls the unit out and tests it. Tight basement stairs and low bungalow ceilings are ordinary to us. You'll hear what's wrong before anything gets replaced.
- Step 3
You decide, we repair
We walk you through the fix and what it involves, then wait for your go-ahead. Most common parts are already on the truck. If something has to be ordered, we tell you the plan and follow up.

Why homeowners call us
- Damp-house know-howPortland laundry rooms grow mildew and basements stay wet. We know what moisture does to dryer vents, washer parts and control boards, so before we call a repair done we look at the room around the machine too.
- Unhurried visitsA rushed diagnostic misses things. We take the extra minutes to pull the panel, look behind the drum and test the drain line. Then we tell you plainly what failed and whether fixing it makes sense on that appliance.
- Every major brandWe're an independent shop, so the whole kitchen and laundry room is fair game: washers, dryers, refrigerators, ranges, ovens, dishwashers, freezers and disposals. A twenty-year-old unit gets the same careful look as a new digital one.
- Wide service reachHomeowners in five Western states reach us the same way. City bungalow, suburban split-level, a house down a gravel road. We set a visit and arrive with tools and common parts ready.
- All major brands, gas & electricOne independent crew for Whirlpool, Samsung, GE, LG, Maytag, Bosch and more.
- Straight answersWhen a repair doesn't make sense, we tell you, sometimes before we even roll a truck.
