Dishwasher Repair near you

A large share of dishwasher repair visits end with a technician lifting out a filter that has never been cleaned. Most machines sold in Australia use a filter you remove and rinse by hand rather than a grinder that chops food waste, and nothing in the kitchen announces its existence — so it silently fills, the water stops circulating properly, and the household concludes the dishwasher has failed.

A surprising number of dishwasher complaints are plumbing complaints. The machine drains into the same waste as the kitchen sink, so a partially blocked sink drain shows up as a dishwasher that will not empty, and a sink full of dirty water after a cycle is the same fault seen from the other side. Grease building up in the waste is the usual culprit in an Australian kitchen, and clearing the machine's own filter will not touch it.

The supply side causes its own share. A tap behind the kickboard that has been knocked half closed, a supply hose kinked when the machine was pushed back after a repair, or a filter screen in the inlet valve clogged with grit after work on the street main will all produce a machine that fills slowly or reports a fill fault. Hard water is the slow version of the same story: scale on the element and the spray arms degrades performance over years rather than overnight.

This is worth knowing before you book, because it changes who you should call. If the sink drains slowly too, the problem is the plumbing rather than the appliance, and altering or clearing the drainage is licensed plumbing work — the QBCC requires a licence for plumbing or drainage work at any value, and other states have their own equivalents.

Installing a dishwasher where there has never been one is not appliance work. It requires a water connection, a waste connection arranged so dirty water cannot siphon back into the machine, and a power supply. In Queensland, plumbing or drainage work requires a QBCC licence at any value of work — unlike general building work, there is no threshold below which it becomes unlicensed. Every state regulates the water supply and drainage in some form, so the safe assumption is that new or altered pipework belongs to a licensed plumber.

The electrical side is equally firm. A dishwasher may plug into a powerpoint inside the adjacent cupboard or be wired to an isolating switch, and either way the wiring is licensed work. NSW requires an electrical licence or certificate before any electrical wiring work, regardless of the cost of the work, where that work means physically installing, repairing, altering, removing or adding to an electrical installation. Energy Safe Victoria's warning covers the temptation directly: unqualified electrical work is not only extremely dangerous, it is also illegal, even for small jobs such as changing powerpoints.

So the division on a typical job is: the technician repairs the machine and may disconnect and reconnect it from existing connections to get at the pump; a licensed plumber handles new taps, a new waste or an altered trap; and a licensed electrician handles a new powerpoint, an isolating switch or a new circuit. Ask which parts of the job each trade is covering before anyone starts, so nothing is left half-connected behind a benchtop.

Because the machine is powered and the leak is at floor level, the order matters. Turn the dishwasher off at its isolating switch or powerpoint if you can reach it without kneeling in water; if you cannot, kill the circuit at the switchboard. Then close the tap that feeds it, which is usually inside the cupboard next to the machine or under the sink. Only after both are off should you start mopping or pulling the machine out.

Do not put your hands on a dishwasher that has given anyone a tingle. NSW safety guidance says to always treat a tingle or slight shock as a warning and never to touch an appliance causing one until it is repaired, to press the test button on your safety switch every three months, and to have a licensed electrician check the switch if it fails. Damaged cords and older style plugs are dangerous and should be replaced rather than taped up and left in service.

Once the machine is safe, deal with the water that has already gone somewhere. Water tracks along the underside of a benchtop and into cabinet bases and floating floors, so lift the kickboard, get air moving into the cavity and photograph everything before it dries — both for an insurer and for a consumer guarantee claim, if the leak turns out to be a fault rather than a blockage.

Consumer guarantees under the Australian Consumer Law are automatic and cannot be taken away by anything a business says or does, and the ACCC states that a warranty against defects is provided in addition to them and does not limit or replace those rights. It also says that after a warranty expires, the guarantee of acceptable quality usually still applies, so a dishwasher failing in its third or fourth year may still be the retailer's problem rather than yours. Misleading you about that is unlawful.

Severity decides the remedy. A major problem — unsafe, very different from its description, carrying a serious defect or several smaller ones that would have stopped the purchase, or unusable for its normal purpose — lets you choose a refund of the full amount paid or a replacement of the same type, with no deduction for the use you have had. A minor problem must be fixed or repaired free of charge, and the business chooses that remedy.

There is one line in the ACCC's guidance that applies to dishwashers by name and is worth quoting when a retailer stalls: businesses are responsible for paying the shipping costs or collecting faulty products that are large, heavy or hard to remove, and the examples given include installed appliances such as stoves or dishwashers. An integrated dishwasher fixed into cabinetry is exactly that, so being told to uninstall it and deliver it to a service centre is not how the law works.

Drain pumps, inlet valves, door seals, latches, spray arms, filters, heating elements and hinges are all routine parts, and a dishwasher with a sound tub is usually worth repairing. The decision tips the other way with a cracked or leaking tub, corrosion at the base, several unrelated components failing in sequence, or a control board that has gone out of production — a common outcome on a premium model whose electronics outlived their supply chain.

Cabinetry is the Australian-kitchen wrinkle that decides plenty of cases. An integrated machine behind a matching cabinet door is sized to that opening, and a replacement has to match the height, the hinge arrangement and the door-mounting system, which narrows the choice considerably and makes repair comparatively attractive. Flooring laid after the original installation can also trap a machine under the benchtop entirely, so mention any floor changes when you book, because freeing it becomes part of the job.

Before paying for a diagnosis on a machine that has been temperamental since it was installed, search the recalls register on Product Safety Australia. Recalls are published there by the ACCC, suppliers have a responsibility to remove a safety risk as quickly as possible, and the guidance for an affected product is to stop using it, keep it out of reach of children and contact the supplier for a repair, replacement or refund without delay.
