Standing water, a puddle on the kitchen floor, or dishes that come out wet and cloudy? We diagnose the real cause on site and repair circulation pumps, drain pumps, spray arms and inlet valves the same way across every major brand.
Most dishwasher calls trace back to a handful of parts: the pumps that move water, the valve that lets it in, the arms that spray it, and the seals that keep it inside. We fix all of them.
Won't drain and leaving dirty water in the tub usually points to a clogged or failed drain pump, a kinked or blocked drain hose, or a stuck check valve. Dishes coming out gritty or still soiled is almost always a weak circulation pump, a cracked spray arm, or spray arm holes plugged with hard-water scale and food debris.
Leaks are their own category: a hardened door gasket, a failed door seal at the base, a loose sump connection, or an overfilling inlet valve that can't shut off. Poor drying is often a dead heating element or vent fan, a failed high-limit thermostat, or a rinse-aid dispenser that stopped releasing. We also handle no-power, no-start, buttons that don't respond, and error codes that keep a cycle from finishing.
A dishwasher hides most of its working parts behind the tub and under the base. We follow a set order so we test the whole water path, not just the obvious symptom.
We run the machine through the failing cycle and watch it fill, wash and drain so we see the actual behavior instead of guessing from a description.
We inspect the inlet valve, float, sump, filter, drain pump and hose, and both spray arms for blockage, scale buildup or cracks.
We meter the circulation and drain pump motors, heating element, thermostats and control board to find open windings, failed relays or a bad element.
You get a firm price for the fix before any work starts. The $89 diagnostic fee is credited toward the repair when you approve it.
Running it again rarely helps once these show up. If you see any of these, it is time to book a visit.
Built-in and integrated dishwashers from higher-end brands use variable-speed circulation pumps, turbidity and temperature sensors, and quiet insulated tubs that are easy to damage during a rushed pull-out. A proper repair means removing and reseating the unit without kinking the fill line or drain hose, and testing sensors instead of just swapping the loudest part.
We use OEM-quality, factory-specified parts so the pump curve, gasket fit and control behavior match what the machine expects. That matters most on panel-ready units integrated with custom cabinet fronts, where a poor reinstall shows immediately.
Local conditions genuinely change how dishwashers age here.
The Front Range runs hard water, so spray arm jets and the inlet valve screen scale up faster than in soft-water regions, which chokes wash pressure and mimics a failing pump. The dry climate at Littleton's roughly 5,350-foot elevation also stiffens and cracks door gaskets sooner, which is a common source of slow leaks. We clean and descale the water path as part of the repair and check the gasket every visit.

Quick Answers
Standing water after a cycle almost always means the dishwasher can't drain. The usual causes are a clogged or failed drain pump, a blocked or kinked drain hose, a stuck check valve, or a plugged filter. Littleton Appliance Repair diagnoses the exact cause on site and repairs it; call (720) 903-2603 to book.
Dishwasher repairs at Littleton Appliance Repair start from $129, with the final price set after an on-site diagnosis. There is an $89 diagnostic service-call fee that is credited toward the repair once you approve the work, so you only pay it separately if you decline the repair.
Poor drying is usually caused by a failed heating element or vent fan, a bad high-limit thermostat, or an empty or clogged rinse-aid dispenser. On many quieter models the vent flap or condensing fan is the culprit. A technician can test these and tell you which part failed rather than replacing everything.
FAQ
Anything else — call any hour, a real person answers.
If the unit is under about eight years old, or it's a premium built-in or panel-ready model, repair is usually the better value since the tub, racks and cabinetry are the expensive parts. We give you the repair cost up front so you can compare it against replacement before deciding.
Yes. We regularly service built-in and panel-ready units integrated with custom cabinet fronts, including brands like Bosch, Miele, Thermador and Cove. We pull and reseat these carefully so the fill line, drain hose and custom panel go back exactly right.
Yes. Front Range hard water scales up spray arm jets and the inlet valve screen, which cuts wash pressure and can look like a failing circulation pump. We descale the water path as part of the repair so the fix actually holds.
We serve Littleton and the Southwest Denver foothills, including Ken-Caryl, Columbine, Chatfield, Roxborough Park and the surrounding Southwest Denver metro, roughly a 25-mile radius.

Our built-in Sub-Zero was keeping the freezer fine but the upper fridge zone was sitting around 55. Turned out to be the dual-evaporator setup, exactly what the tech guessed on the phone. Brian had the sealed system diagnosed the first visit, ordered the part, and had us back to normal within the week. He didn't try to sell us a new unit like the last place did.
One of the dual-stack burners on our Wolf range would click and click but never light. He mentioned it's common up here because the burners need to be calibrated for the altitude, which no one had ever told us. Relit perfectly after and he adjusted the others while he was at it.
Fixed our Sub-Zero the same week we called. Fair price, no upsell.
Our dual-zone wine cabinet had drifted so the bottom zone wouldn't hold temp and there was condensation collecting on the glass. They diagnosed it quickly but the part had to come from the manufacturer and took about four days, so we were without it for most of a week. Once it arrived the fix was solid and both zones are holding right where they should. Worth the wait, just be ready for the parts delay on these.
Miele dishwasher wouldn't drain, standing water in the bottom every cycle. Bad drain pump. In and out in about an hour and he cleaned out the filter housing that was part of the problem too.
The door gasket on our 15-year-old Sub-Zero had gotten brittle and it was sweating around the seal. New OEM gasket and it seals like new again. Appreciated that they used the factory part instead of some universal thing.
Thermador wall oven quit heating right before we were hosting. Called in the morning and they got someone out that same afternoon. Bad igniter. He had the part on the truck and we still made our dinner.
Ice maker in our Sub-Zero was making cloudy hollow cubes and barely any of them. He flushed the system, replaced a valve, and now it actually keeps up when we have people over. Nice guy, wore booties in the house without being asked.
Solid work on our Bosch dishwasher, the drain pump had failed. The only thing is the $89 service call fee felt a little steep before I knew they credit it toward the repair. Once I proceeded it came off the bill, so no real complaint, just wish I'd understood that up front.
Our Viking freezer was building up a wall of frost and not defrosting on its own. Turned out to be the defrost heater. Fixed it and explained what was going on so I understood why it happened.
Two burners on our Wolf cooktop wouldn't spark. Tech recalibrated them for the elevation and swapped the igniters. Works better than it has in years honestly.
Warm upper zone on our Sub-Zero, classic apparently. They knew exactly what it was, ordered the evaporator part, and came back to install it a couple days later. Honest and easy to deal with the whole way through.
Not many people around here will even touch a Gaggenau. These guys did, got the control board sorted, and were straight with me about the cost of the part on a unit this expensive.
Miele steam oven throwing an error and shutting off mid-cook. The tech was great and clearly knew the unit, but he ran about 40 minutes behind the window they gave me and I had to shuffle some things around. Fixed it in one visit though and it's been perfect since, so I'd still call them again.
Had them out for our built-in outdoor grill that wasn't lighting evenly. Didn't expect them to do outdoor units but they did and dialed it in for the altitude. Grilling season saved.
Quick, clean, and they answered when I called at 9pm the night before. Dishwasher's draining again.
This was a big one, the sealed system on our Sub-Zero failed and that's a job a lot of shops won't take on. They did it right, used factory-spec parts, and stood behind the work. Given it's a $12k built-in I'm glad I found someone who actually knew these inside and out instead of just replacing the whole fridge.
Wine fridge kept fogging up on the door and the temp was bouncing around. Fixed same visit and no more condensation.
