What dishwasher calls look like in Mississauga

New-build dishwashers in Mississauga have a signature problem, and it is not the appliance. Builder installs are done at volume and at speed, and the step most often skipped is the drain high-loop — the simple loop of hose secured up under the countertop that stops waste water flowing back into the machine.

Without it, dirty water siphons back between cycles. The owner gets odour, standing water and dishes that never come out properly clean, and reasonably concludes the dishwasher is bad. It is not: it has been installed incorrectly since the day the house was handed over. We find this several times a month in the newer subdivisions and the Square One towers alike.

Fixing it takes minutes and is permanent. The other builder-install issue we see is the garbage disposal knockout plug left in place, which stops the machine draining at all and presents exactly like a failed pump. Both are worth checking before anyone pays for a part.

— FAQ

Dishwasher repair in Mississauga — questions

Our dishwasher has never drained properly since the house was new. Is it defective?

Usually it is the installation rather than the appliance. A missing drain high-loop lets waste water siphon back into the machine, producing odour and standing water from day one. It takes minutes to correct and it is permanent.

What is the knockout plug and why does it matter?

New garbage disposals ship with a plug in the dishwasher inlet, and it has to be knocked out during installation. If it was missed, the dishwasher cannot drain at all — and it looks exactly like a failed pump. We check it before quoting anything.

My machine is two years old. Will the manufacturer cover the repair?

Possibly, and we check the model and serial before quoting. If it is covered we tell you to go through the manufacturer instead of paying us. If the fault is an installation issue rather than a defect, that is generally on the builder — and we document what we find so you can take it up.
