Common Dishwasher Issues We Solve

Even a premium appliance like a Bosch dishwasher can run into problems. Below are some of the most frequent issues customers experience—though we are fully capable of resolving any malfunction, no matter how complex or obscure.

Dishwasher not starting or turning on

A Bosch dishwasher that refuses to power up could signal anything from a failed control board to a faulty door latch sensor or even an issue with the power supply itself. We don’t just look at the surface—we check internal circuitry, wiring harnesses, and user interface boards to ensure every potential problem is covered.

Water not draining properly

When standing water is left behind after a wash cycle, it’s often due to a blocked filter, a failing drain pump, or kinks in the drain hose. Bosch models, with their low-noise drain systems, require careful dismantling to diagnose these problems correctly. Our techs use non-invasive methods to trace drainage issues back to their root without damaging delicate internal components.

Strange noises during operation

Unusual grinding, buzzing, or humming noises typically indicate a problem with the motor bearings, pump assembly, or wash arm. Bosch dishwashers are known for quiet operation, so any unexpected sound usually points to a specific failure. We investigate using targeted tests to isolate where the sound originates—then repair or replace the faulty part accordingly.

Leaking water from the dishwasher

Leaks are more than an inconvenience—they can lead to long-term flooring damage and mold. Whether it’s a cracked door seal, a loose sump assembly, or a misaligned water inlet valve, we inspect every seam, joint, and gasket to locate the source and stop it in its tracks. Bosch dishwashers often feature advanced AquaStop systems, which we also test and recalibrate when needed.

Dishwasher not filling with water

If the appliance isn’t drawing water as it should, possible culprits include a stuck float switch, a malfunctioning water inlet valve, or clogged inlet screens. Our technicians understand how Bosch regulates water levels and apply detailed checks to restore flow and pressure balance.

Error codes or flashing lights on the control panel

Modern Bosch dishwashers come with digital displays and complex error messaging systems. Whether it’s an E15 flood code, E24 drain error, or an intermittent flashing LED, we interpret each code correctly and get to work on a fix—be it software reset, sensor replacement, or a deep clean of the internal compartments.

We’re proud to be one of the most trusted dishwasher repair services in Toronto. Our customers appreciate our quick response times, transparent pricing, and reliable workmanship. Here’s what some of them have to say:

★★★★★

My dishwasher suddenly stopped mid-cycle and wouldn’t drain at all. I called them late in the afternoon and someone showed up the next morning. Turned out to be a busted drain pump — they had it fixed within an hour. Super friendly and no surprises with pricing.

Alise M., North York

★★★★★

Fast, honest, and knowledgeable! Our older unit kept showing flashing lights and wouldn’t start. I assumed it was done for, but they replaced a small sensor and saved us the cost of a new machine. Great experience from start to finish.

Robert J., Etobicoke

★★★★★

I called about a leaking dishwasher that was soaking our kitchen floor. The tech arrived the same day, found a torn gasket and replaced it right away. Very impressed with the professionalism and how clean they left the space.

Marina S., Scarborough

★★★★★

What I liked most was how clearly they explained the problem. My Bosch wasn’t filling with water — apparently a valve issue. The guy had the part in his van and got it working that same visit. Definitely using them again if anything breaks.
