Dishwasher installation in Ottawa

A dishwasher is the one appliance in the kitchen that is permanently connected to hot water, a drain and a live circuit at the same time, and it sits inside a cabinet where nobody looks for months. Many of the dishwasher leaks we repair in Ottawa trace back to the original hook-up: a supply line that was over-tightened and cracked, a drain hose pushed straight into the disposal without a high loop, or a unit that was never secured to the counter and slowly walked forward every time the loaded door was opened. None of those faults show up on day one. They show up in year two, under the cabinet floor, usually in a finished kitchen.

Doing it right takes a technician about an hour. It costs a fraction of what a soaked subfloor costs, and it protects the manufacturer warranty, since manufacturer warranties generally exclude damage caused by an incorrect installation. That is why homeowners in Barrhaven, Stittsville and the Glebe call us rather than relying on the delivery crew, who are paid to drop the box, not to connect it.

• Removal of the old unit. We shut off the water, disconnect the supply, drain and power, and slide the old dishwasher out of the opening, taking care with the floor and the cabinet face.
• Inspection of the opening. We check the cabinet width and height, confirm the floor is level enough for the levelling legs to work, and look for old water damage that you will want to know about before the new unit covers it up.
• Water supply. We connect the hot-water line with a new braided stainless supply hose and add a proper shut-off valve if one is missing. Older Ottawa homes in Alta Vista, Carlington and Overbrook often have a corroded compression valve under the sink that needs replacing at the same time.
• Drain with a high loop or air gap. The drain hose is routed up to the underside of the counter before it drops to the sink drain or disposal. Skipping that loop is how dirty sink water ends up in the bottom of a dishwasher.
• Electrical connection. Hard-wired or plug-in, the connection is made in the junction box with a strain relief, not twisted together under the unit.
• Levelling and anchoring. The unit is levelled front to back and side to side, then secured to the counter or the side cabinets so it cannot tip when the door is loaded with plates.
• Full test cycle. We run a complete cycle, check every connection for drips, and confirm the drain pumps out cleanly and the door seals. Packaging removal is something to request when you book.

Standard 24-inch built-ins are the bulk of what we install, but the process changes with the type of unit.

• Panel-ready and integrated dishwashers from Bosch, Miele and Fisher & Paykel need the cabinet panel fitted and the door spring tension adjusted for the extra weight; otherwise the door drops open.
• 18-inch compact units are common in Centretown and Sandy Hill condos and often need a filler strip.
• Drawer dishwashers mount differently and need a dedicated drain routing for each drawer.
• Portable and countertop units connect to a faucet adapter and still benefit from a proper check of the adapter and the drain.

If the new dishwasher is replacing one that may still be worth fixing, see dishwasher repair in Ottawa and dishwasher repair cost in Ottawa before you buy; a failed pump is sometimes a smarter fix than a new machine.

No shut-off valve. A surprising number of Ottawa kitchens have the dishwasher supply teed straight off the hot-water line with no valve. We add one, so the next service call does not require shutting off water to the whole house.

Old copper supply line. Rigid copper lines work-harden and split. We replace them with braided stainless.

Drain hose pushed into a disposal with the knock-out plug still in place. The dishwasher fills and then floods because it cannot drain. This is one of the most common “brand-new dishwasher is broken” calls we get, and it is an installation error, not an appliance fault. If your existing unit is doing that, our dishwasher not draining in Ottawa page walks through it.

Countertop the unit cannot anchor to. Quartz and granite counters cannot take the top-mount screws. We use side-mount brackets to the adjacent cabinets instead.

Floor higher than the cabinet opening. New tile or hardwood laid after the original dishwasher went in can leave less than the 34 inches most units need. We tell you before we pull the old unit whether the new one will fit, and what the options are.

You get the dishwasher installation price in writing and approve it before anything is disconnected. It reflects the type of dishwasher, whether an old unit has to come out, and whether the supply valve, drain or electrical connection needs correcting. Once you approve it, nothing is added without your agreement after the technician gets under the counter.

If you would rather have us look at a failing dishwasher before you decide to replace it, book a diagnostic visit; the fee is credited to the repair if you proceed, and you get a straight answer on whether to repair or replace. Visits are booked between 7 AM and 9 PM; after 9 PM and before 7 AM a $100 flat after-hours fee applies. Outside a 30 km radius of downtown Ottawa a travel charge may be added; you will know when you book.

We confirm the warranty terms for a dishwasher installation when we send your quote.

All of Ottawa: Kanata, Barrhaven, Nepean, Orléans, Gloucester, Stittsville, Westboro, the Glebe, Centretown, Alta Vista, Riverside South and Findlay Creek. Across the river, Hull, Aylmer and the rest of Gatineau are covered by the same bilingual team; see appliance installation in Gatineau, with French service available on request. In business since 1995, we install and repair dishwashers on both sides of the river.

Clear the cabinet under the sink so we can reach the valve and the drain. Have the new dishwasher in the kitchen, still in its box, and leave the old one hooked up: the way it was connected tells us a lot. If the new unit is panel-ready, have the panel on site.

Bought a gas range at the same time and want both connected on one visit? Mention it in your request: on the Ontario side a TSSA-certified technician makes the gas hook-up and leak-tests it, and we will try to schedule both in a single trip. See stove and range installation in Ottawa and washer and dryer installation in Ottawa if you are outfitting the whole house. A same-day install is sometimes possible; either way, the booking is only firm once we have called or texted you with a time window.
