The short answer
Gleadale Appliance services repairs dishwashers in South Pasadena homes, including Cove by Sub-Zero, Thermador and Viking models. We diagnose drainage, leak, heating, latch and error-code problems on site and explain your repair options before any work begins.
When a dishwasher stops draining, leaks onto the floor, or leaves dishes dirty, the kitchen backs up fast. Gleadale Appliance services repairs dishwashers in homes across South Pasadena (ZIP 91030), about 6 miles east of our base in Glendale. We focus on premium kitchens, including Cove dishwashers from the Sub-Zero Group, Thermador and Viking models, and the panel-ready units that sit next to Sub-Zero refrigerators and Wolf ranges. We are an independent repair company, not affiliated with any manufacturer. Our goal is to find the actual cause, explain it in plain terms, and fix it so you can stop washing dishes by hand.
Dishwasher problems we fix in South Pasadena homes
Most dishwasher calls fall into a few patterns. Each one has a short list of likely causes, and a careful diagnosis keeps you from paying for parts the machine doesn't need.
- Water left standing in the tub after a cycle, usually from a clogged filter, drain pump, check valve or kinked drain hose
- Leaks at the door, under the unit, or into the cabinet next to it
- Dishes coming out cloudy, gritty or still dirty because of spray arm, circulation pump or water inlet problems
- Dishes not drying, or water not heating, often traced to a heating element, thermostat or control issue
- Door latch failures that keep the cycle from starting
- Error codes, blinking lights or a control panel that won't respond
- Grinding, humming or loud noises during a wash

Panel-ready and integrated dishwashers
Many premium kitchens use dishwashers with custom cabinet panels so the appliance blends into the cabinetry. Cove dishwashers from the Sub-Zero Group and many Thermador and Viking models are built this way. That design looks clean, but it means the technician has to remove and reinstall the unit carefully, protect the panel and surrounding cabinets, and set the door spring tension correctly for the panel's weight. If the tension is off, the door can drop open or refuse to stay closed.
We also keep the rest of the kitchen in mind. A dishwasher often shares a cabinet run with a Sub-Zero refrigerator or sits near a Wolf range. We work around those appliances with care, and we can look at them on the same visit if they're giving you trouble too.
What happens during a repair visit
We start by asking what you've noticed: when the problem began, which cycles it affects, and any codes or sounds. Then we test the machine directly. That means checking the drain path, inspecting the filter and spray arms, verifying water fill and heating, and reading any stored fault information the control board provides.
Once we know the cause, we tell you what failed, what the repair involves, and whether the part is likely to be on hand or needs to be ordered. You decide whether to go ahead. If the repair isn't worth it on an older machine, we'll say so plainly.
Tell us what your appliance is doing.
Quick checks before you schedule
A few simple things are worth trying first. They can save you a visit, and if they don't help, they give us useful information.
- Pull out and rinse the filter at the bottom of the tub; a clogged filter is a common cause of poor draining and dirty dishes
- Run the kitchen faucet until the water is hot before starting a cycle
- Make sure the garbage disposal, if the dishwasher drains through it, is clear and that a new disposal's knockout plug was removed
- Check that nothing on the bottom rack is blocking the spray arms
- Look under the sink for a kinked drain hose or a closed water supply valve
