Dishwasher installation in Ottawa & Gatineau
Most 'broken' dishwashers we see in the first year were installed with a drain hose routed wrong, a missing high loop, or a water supply that was never fully opened. Installing it properly is the cheapest repair there is. RepairWell installs and replaces built-in dishwashers in Ottawa and Gatineau where the existing connections are in place and correct. We don't take away old appliances.
What the installation includes
- Disconnecting and removing the old dishwasher from the cabinet (we don't take it away)
- Connecting to the existing water supply valve with a new supply line
- Routing the drain hose with a high loop or air gap to the sink drain or disposer
- Connecting a cord-and-plug dishwasher to an existing receptacle under the sink
- Levelling, securing to the counter or cabinet, and running a test cycle with a leak check
- Written record of the installation on the same one-page form we use for diagnostics
What your home needs already
- A working shut-off valve under the sink for the dishwasher supply
- A drain connection at the sink tailpiece or disposer inlet
- Either a receptacle under the sink (for cord-and-plug models) or an existing dedicated circuit for a hard-wired model
- A cabinet opening that fits the new unit (standard 24 in / 61 cm; compact 18 in / 46 cm)
Work that needs a licensed trade
In Ontario, electrical work done for hire must be performed by a licensed electrical contractor (ECRA/ESA licence); a homeowner may do electrical work on their own home only after filing a notification with the Electrical Safety Authority. RepairWell connects cord-and-plug dishwashers to an existing receptacle. If your kitchen needs a new circuit, a new receptacle, or a hard-wired junction box installed, that is electrical contracting work and we'll tell you to book a licensed electrician first. Likewise, if there is no shut-off valve or the drain tailpiece needs replacing, a plumber may be required. In Quebec, work that requires an RBQ licence or a master electrician is done by a licensed contractor.
How it goes
- Confirm fit and connections by phone. Model number of the new unit, photo of the space under the sink, and whether the existing dishwasher is hard-wired or plugged in.
- Install and connect. Old unit out, new unit levelled and secured, supply, drain and power connected as above.
- Test and document. Full cycle with a leak check at every connection; written record left with you.

Questions
Can you install a dishwasher where there has never been one?
Only once the plumbing and electrical rough-in exist. Those are licensed-trade jobs; after they're done, we install and connect the unit.
My new dishwasher is hard-wired. Can you connect it?
If an existing hard-wired connection with a junction box is already in place from the previous dishwasher, yes: our technician connects it at the existing junction box, like for like, on the same circuit. Installing a new circuit or box is electrical contracting work for a licensed electrician.
Do you install dishwashers bought elsewhere?
Yes. Send us the model number and we'll confirm fit and connections before booking.
