Dishwasher repair solutions for homes across Ottawa & the surrounding region. Covering every common failure mode, from drainage & cleaning issues to electronic faults & water leaks.
Dishes coming out dirty, streaked, or covered in food residue point to a few specific failure points: blocked spray arms, a worn wash motor, a failed heating element preventing proper water temperature, or a faulty detergent dispenser releasing detergent at the wrong cycle stage. Hard water deposits on spray arm jets are also common in the Ottawa area. We test water temperature during the wash cycle, inspect the wash assembly, and repair the exact component causing the cleaning failure.
A dishwasher that finishes a cycle with water sitting at the bottom is the most common service call we get. The cause is usually the drain pump itself, a clogged filter or sump, a kinked drain hose, or a blocked air gap or garbage disposal connection. Modern units also use a check valve that can stick open and prevent draining entirely. We diagnose the exact failure point, clear blockages where applicable, and replace failed dishwasher pumps and check valves with manufacturer-approved parts.
When dishwasher buttons stop responding, the display dims or flashes, or the unit shows error codes mid-cycle, the cause is usually the main electronic control board, the user interface board, or a touchpad membrane that's worn out from years of use. Bosch dishwashers commonly throw E15, E22, and E24 codes; Samsung units use 4C and 5C codes; LG units use IE and OE codes. We diagnose the meaning of the specific code and repair or replace the failed control component in your dishwasher.
Water on the floor under or around a dishwasher is a high-priority repair because of the property damage risk to flooring, subfloor, and adjacent cabinetry. Common sources are a worn or torn door gasket, a failed water inlet valve dripping into the tub, a cracked sump or hose clamp, or a stuck float switch causing overflow. Our technicians identify the exact leak source rather than guessing, and replace the failed component with a written warranty on the dishwasher repair.

Modern dishwashers display brand-specific error codes that pinpoint the underlying failure. Decoding the right code is the starting point of an efficient repair, not the ending point, multiple components can produce the same code, and our diagnostic process verifies the actual cause before replacing parts.
Bosch dominates the dishwasher market in Canadian kitchens, and the most frequent codes we encounter are E15 (water in the base / leak protection activated), E22 (filter blockage / drain pump issue), E24 (drain hose blockage or drain pump failure), and E25 (drain pump cover not seated correctly). The E15 code in particular requires careful diagnosis because the leak-detection float can trigger from condensation or a single stray drop, masking a more serious leak elsewhere in the unit.
Samsung dishwashers commonly throw 4C or 4E (water supply error), 5C or 5E (drain error), OC (overflow / water level too high), and LC or LE (leak detected). Modern Samsung units with Wi-Fi connectivity also display these codes through the SmartThings app, sometimes before they appear on the unit itself.
LG units use IE (water inlet failure), OE (drain failure), FE (overflow error), and LE (motor lock). LG dishwashers with their proprietary Direct Drive motor system have specific motor-fault diagnostic procedures that differ from belt-driven competitors.
Whirlpool-family dishwashers (which includes Maytag, KitchenAid, and Inglis) typically use sequenced light blinks rather than displayed codes on older units, and F-series codes on newer ones, F1 through F8 ranges from thermistor failure to drain pump issues. The blink-sequence diagnostic on older units requires the technician to know the specific decoder pattern for each model year.
The single most common dishwasher service call. Causes range from a simple food blockage in the drain filter (a quick fix) to a failed drain pump (a parts replacement) to a kinked drain hose or blocked air gap behind the sink (sometimes a plumbing issue rather than a dishwasher issue). A dishwasher that has never been hooked up correctly to a garbage disposal, with the disposal's knockout plug still in place, will also fail to drain, and we see this surprisingly often in homes where the dishwasher was a later addition.
The most damaging dishwasher failure category because of the property risk to flooring and adjacent cabinetry. The most common sources are a worn or torn door gasket, a failed water inlet valve dripping into the tub, a cracked sump or hose connection, or a stuck float switch causing the unit to fill past the safe water line. Some leaks only appear during specific cycle phases, wash but not rinse, for example, which makes diagnosis a process of running the cycle and watching for the source rather than guessing from the puddle alone.
If the dishwasher runs a complete cycle but dishes come out dirty, streaked, or coated with food residue, the issue is usually in the wash assembly or water heating system. Spray arm jets clogged with hard water deposits or food particles reduce wash pressure. A failed heating element prevents water from reaching the temperature needed to activate detergent and dissolve grease. The detergent dispenser door can fail to open, releasing detergent at the wrong time. Each is a different repair, proper diagnosis matters.
A dishwasher that's completely unresponsive, no lights, no buttons, no water, is usually a power issue: a tripped breaker, a failed door latch (the unit won't start unless the door is sensed as fully closed), or a failed thermal fuse on the control board. Worn touchpads on older units can also fail in ways that look like complete electrical death because the user interface stops registering inputs.
Dim displays, buttons that need to be pressed multiple times, lights that flicker, or controls that respond to some inputs but not others all trace back to the user interface board or the main electronic control board. Modern dishwashers with capacitive touch controls can also have moisture-related sensitivity issues, water entering the door panel through a worn gasket can cause phantom button presses or unresponsive zones until the panel dries out.
Grinding, humming, or rattling during operation typically comes from the wash motor, drain pump, or chopper assembly that breaks up food particles before they reach the drain. A foreign object, a piece of glass, a fruit pit, a small bone, caught in the chopper or pump impeller is a frequent cause that an experienced technician can clear quickly.

Same-day service is available across Ottawa, Kanata, Nepean, Orléans, Barrhaven, Gloucester, and Stittsville depending on technician availability when you call. We also offer 24/7 on call service for after-hours emergencies, particularly important when a dishwasher is actively leaking under hardwood floors or into adjacent cabinetry where every hour increases the damage.
Yes. Our technicians are professional, licensed, and insured. Insurance matters specifically for built-in dishwasher repair because the work often requires pulling the unit out from under cabinetry, disconnecting plumbing, and accessing electrical connections, situations where the risk of incidental damage to floors or cabinets is higher than with countertop appliances.
Note the exact code and call us. The code points to the failure category but not always the exact failed part, for example, a Bosch E15 code can be triggered by an active leak, a faulty leak sensor, or simply condensation in the base pan. Our technician will read the code as a starting point, then verify the actual cause before recommending a repair. Don't run the cycle again until the diagnosis is complete; some codes indicate active leaks that worsen with continued use.

Ottawa’s water is moderately hard, which causes progressive mineral buildup inside your unit. This often leads to white film on glassware, clogged spray arm jets, and structural issues like calcified water inlet valves or scaled heating elements. Routine descaling every 2–3 months can help extend the life of your dishwasher.
We service all common configurations found in Ottawa homes and condos, including standard 24-inch built-ins, drawer-style units, 18-inch compact models, and portable freestanding dishwashers. Our technicians handle the careful disconnection and pull-out required for built-in units to protect your cabinetry.
Most dishwasher failures are worth repairing because standard components, like drain pumps, control boards, or door gaskets, cost significantly less than a new unit. Replacement is usually only recommended if the inner tub is rusted or cracked, if multiple parts fail at once, or if the unit is more than 10–12 years old.
We service every major brand sold in Canada, including Bosch, Samsung, LG, Whirlpool, Maytag, KitchenAid, Kenmore, Frigidaire, and GE. Our technicians are fully trained to handle integrated panel-ready units as well as smart dishwashers with Wi-Fi and remote diagnostics.
