What Happens When You Call
You describe the problem and the dishwasher’s make and model over the phone, and we book a same-day slot where the schedule allows. The technician arrives, tests the machine with the relevant tools instead of swapping parts by guess, and writes up a quote for you to approve before touching anything. We arrive with the parts that most commonly fail for your model, so most repairs are finished the same visit, backed by a 1-year warranty on parts and labour.
Common Dishwasher Problems We Fix
Most dishwasher calls in Montreal come down to a short list of causes. Here is what each usually means and what happens once a technician is on site.
Won’t Start
Usually a tripped breaker or loose connection, a door latch that isn’t registering closed, or a control panel that needs a reset, and occasionally a child lock feature left switched on by accident. Dishwashers wired directly instead of plugged into an outlet sometimes lose power at the switch under the sink rather than at the breaker panel, which is easy to miss when troubleshooting. The technician checks power and the latch first, since those are the quickest to rule out, then tests the control board and start switch before opening anything else up. Dishes left sitting inside a dishwasher that won’t start are safe to leave; running it before it’s fixed usually isn’t.
Won’t Drain
Usually a clogged drain hose, a blocked air gap or garbage disposal knockout plug, or a failed drain pump. Improper installation, particularly a drain hose that loops the wrong way or a knockout plug that was never removed on a new garbage disposal, causes the same symptom on an otherwise healthy machine. The technician clears the hose and air gap first, since that’s the most common cause, then tests the pump itself if standing water remains after that.
Leaking
Usually a damaged door seal, a cracked or disconnected drain hose, a faulty water inlet valve, or a dishwasher that wasn’t installed quite level. Water pooling right at the front of the door usually means the seal; water appearing underneath the cabinet more often points to a hose or valve. The technician traces the water to its source along the base of the machine, replaces the failed seal or hose, and checks that the unit sits level and the door latches fully before leaving.
Not Dispensing Soap
Usually a blocked detergent compartment, a stuck dispenser mechanism, dishes loaded in a way that blocks the dispenser door from opening, or low water pressure into the machine. Detergent pods left in a damp dispenser between cycles sometimes swell and jam the latch, which looks like a mechanical fault but isn’t one. The technician checks the dispenser latch and spring mechanism, and confirms water supply and pressure are adequate before replacing the dispenser assembly.
Dishes Not Coming Out Clean or Dry
Usually clogged spray arms, a failing heating element, incorrect water temperature, or dishes loaded in a way that blocks the spray pattern. Cloudy glassware specifically is more often a water chemistry problem than a mechanical one, covered separately below. The technician clears the spray arm jets, tests the heating element and water temperature at the inlet, and checks the rinse aid dispenser, since all four commonly combine to leave dishes wet or spotted.
White Film or Cloudy Spots on Dishes and Glasses
Usually hard water mineral deposits, a worn rinse aid dispenser, using the wrong detergent for your water, or a spray arm not distributing water evenly. Tap water hardness varies from one house to the next, which is why two households with the same dishwasher can have very different results. This is more a water chemistry issue than a mechanical fault, and our guide to dishwasher white film covers the causes and fixes in detail, including when it’s worth calling us to check the machine itself rather than just changing detergent.
Repair or Replace?
Most dishwasher repairs cost well under the price of a new unit, and every repair we do carries a 1-year warranty on parts and labour. Once a dishwasher passes about 10 years old, or the main control board or motor pump assembly has failed, replacement can work out cheaper over time than repeated repairs, especially on a unit that’s already had more than one part fail in the past couple of years. Hydro-Quebec’s energy efficiency guidance is a useful reference on what an older dishwasher costs to run in hot water and electricity, and the Office de la protection du consommateur outlines what a fair repair quote should include, which matches how we work: nothing starts until you’ve approved the price in writing. We’ll always tell you plainly if a repair isn’t worth the cost for your specific machine. If your model shows an error code, the manufacturer’s support pages, such as Bosch’s, list what each one means for that specific model.
How Long a Dishwasher Repair Takes
Most single-part repairs, like a door seal, a water inlet valve, a dispenser or a drain pump, are finished within the same visit once the technician is on site, since these parts are reached without removing the whole unit from the cabinet. Control board replacements take a little longer and are usually scheduled once the exact fault and part are confirmed. Either way, you get a time estimate along with the written quote, before anything is opened up.
We cover Montreal, Laval, the West Island, the South Shore and the North Shore, and most calls in these areas can be booked for the same day. Whatever the symptom, call (514) 667-4479 and describe what the dishwasher is doing, and for how long, so we can send a technician with the right parts.

Dishwasher Repair FAQ
Usually food residue trapped in the filter, mold or mildew around the door gasket, or hard water deposits building up inside the machine. A dishwasher that sits unused for a few days between loads tends to develop odor faster than one run daily, since standing water in the sump has time to grow bacteria. Scrape dishes before loading, clean the filter monthly, wipe the gasket, and run an empty hot cycle with a dishwasher cleaner or a cup of vinegar. If the smell doesn't clear up after that, the drain hose or air gap likely needs a closer look.
Usually a clogged drain hose, a blocked air gap or garbage disposal knockout, or a failed drain pump. If a garbage disposal was installed recently, check that the knockout plug inside it was actually removed, since that's an easy step to miss and it blocks the dishwasher's drain path entirely. Check and clear the filter and air gap first, since food debris collecting there is the most common cause; if water still sits in the bottom after that, the drain pump has likely failed and needs replacing.
Usually a blocked detergent compartment, a stuck dispenser latch, dishes loaded in a way that blocks the dispenser door, or low water pressure. Clean the compartment of any hardened detergent residue and check that nothing is blocking the dispenser door from swinging open; if it still won't release, the dispenser mechanism itself needs replacing.
Usually a damaged door seal, a clogged or cracked drain hose, a faulty water inlet valve, or a machine that isn't quite level. Check the door gasket for visible cracking or gaps first; if the leak is coming from underneath rather than around the door, the inlet valve or drain hose needs a technician to access.
Check the power supply first: a tripped breaker or loose cord stops a dishwasher from starting outright, and this includes the switch under the sink on units that are hardwired rather than plugged in. If power is fine, a door latch that isn't fully closing, or a control panel that needs a reset, is the likely cause. Try unplugging the unit for a minute to reset the control board before calling; if that doesn't work, the latch or board likely needs replacing.
Usually improper loading that blocks the spray pattern, a failing heating element, low water temperature, or an empty rinse aid dispenser. Plastic containers are the worst offenders for staying wet, since plastic doesn't hold heat the way ceramic or glass does, which is normal and not a fault. Load dishes so water can reach every surface, keep the rinse aid topped up, and set the water heater to at least 49 degrees Celsius. If dishes are still wet after that, the heating element needs testing.
We aim to finish the repair on the first visit. Our technicians arrive with the tools and the parts that most commonly fail for your model, based on what you tell us when you book, so most jobs don't need a second trip. On the rare occasion a specific part has to be ordered, we'll tell you upfront and give you a realistic timeline for the return visit.
Remove any dishes from the machine and clear the area around it, including anything stored in the cabinet next to it, so the technician can get straight to work without delay. Having the make and model number ready, usually printed inside the door frame, also helps if a part needs to be ordered. That's really all that's needed on your end.
