The short answer
Viking Appliance Services repairs Viking and Thermador dishwashers in San Marino, including leaks, drainage problems, error codes, and poor cleaning or drying. We carefully remove and reinstall built-in and panel-ready units, and we explain the fault before starting work.
Many San Marino kitchens have built-in, panel-ready dishwashers that sit flush with custom cabinetry. When one leaks or stops partway through a cycle, it can damage wood floors and cabinet bases, not just leave you with dirty dishes. Viking Appliance Services repairs Viking and Thermador dishwashers in homes throughout San Marino (91108). We regularly work in kitchens where these dishwashers sit alongside Sub-Zero refrigeration and Wolf cooking equipment. We're an independent repair company based in Los Angeles, about 15 miles northwest of San Marino. We diagnose the actual fault before replacing any parts.
Dishwasher problems we see most often
Most dishwasher calls come down to a handful of faults. Some are simple, like a clogged filter. Others involve a failed pump, heater, or control board. We test components instead of guessing, so you don't pay for parts that weren't the problem.
- Water left in the tub after a cycle, usually from the drain pump, a check valve, or a blocked drain hose
- Leaks at the door or under the unit, from worn door gaskets, a cracked spray arm, or a loose inlet connection
- Dishes coming out dirty or gritty, often from clogged spray arms, a dirty filter, or weak circulation
- Dishes that don't dry, which can point to the heating element, rinse aid dispenser, or drying fan
- Error codes, blinking lights, or a control panel that won't respond
- Cycles that stop partway, run far too long, or won't start
- Grinding, humming, or knocking noises during washing or draining
- Cloudy glassware or a white film from mineral buildup

Built-in and panel-ready dishwashers
Integrated dishwashers with a custom wood panel that matches the surrounding cabinets are common in San Marino homes. To reach the drain line, water supply, and leveling feet, the unit has to come out of its opening carefully. Then the panel has to go back on aligned with the cabinets next to it. We protect flooring and cabinet faces when we slide a unit out. Afterward, we check the door spring tension, because a heavy panel changes how the door balances.
Viking and Thermador dishwashers use model-specific parts and diagnostic modes, and we come prepared for those models. If a part has to be ordered, we tell you what failed and why before scheduling the return visit.
What happens during a repair visit
We start by asking what you've noticed: when the problem began, any codes on the display, and whether it happens every cycle or only sometimes. Then we run a test cycle or the unit's diagnostic mode, check water supply and drain flow, and inspect the parts that match the symptom. We explain the fault and the fix before any work starts. When the needed part is common, many repairs are finished on the first visit. Other repairs need a part ordered for your specific model.

Quick checks before you call
Some problems are easy to rule out on your own. These checks are safe and may save you a visit:
If none of these help, write down any error code and the model and serial numbers. They're usually printed on the edge of the door or the side of the tub. That information helps us bring the right parts.
- Pull out and rinse the filter at the bottom of the tub; a clogged filter causes poor cleaning and slow draining
- If a garbage disposer was recently installed, make sure the knockout plug in its dishwasher inlet was removed
- Confirm the breaker hasn't tripped and the door latches fully
- Look for a control lock or delay-start setting on the control panel
- If you see water on the floor, stop using the dishwasher and shut off the water supply valve under the sink
Repair or replace?
A dishwasher with a failed pump, heater, or door seal is usually worth repairing. That's especially true for a built-in unit that's sized and paneled to fit your cabinets, because replacing it can mean matching dimensions, refitting the custom panel, and sometimes adjusting the opening. Repair may not make sense if the tub is corroded or an older unit has had repeated control failures. In that case, we'll tell you plainly so you can decide what to do.
