Dishwasher repair at the source of Snohomish County's water

The water in an Everett dishwasher comes straight from the city's own system: Spada Reservoir, the Chaplain Reservoir treatment plant built in 1983, and mains that also feed most of the county. Total hardness runs between 10.2 and 15.8 parts per million, and the city adds soda ash to raise pH and alkalinity, so the average pH sits around 8.1. For a dishwasher that combination means no mineral crust on the heater or spray arms, but detergent that foams readily and, at full doses, slowly etches glass. Many of the 'everything comes out cloudy' calls we take are about chemistry, not parts.

The machines vary with the housing. Rental kitchens around Everett Mall and along Evergreen Way mostly hold builder-grade Whirlpool, GE, Frigidaire and Samsung dishwashers with plastic tubs, often draining through a disposer. Owner-occupied homes near Silver Lake run more Bosch and KitchenAid models with manual filters and stainless tubs. Compact and drawer models appear in a few smaller condos. In apartments the dishwasher shares a short cabinet run with the sink and disposer, so on every drain or leak call we check all three connections. We carry the drain pumps, inlet valves, latches and heaters that fail most in both kinds of kitchen.

Apartment dishwashers often suffer from the opposite of overuse. Some tenants rarely run them, using the racks for drying or storage, and a dishwasher that sits dry for months can develop a sticky pump, a stiff door gasket or a check valve that won't seat. When it finally runs, it hums without draining or leaks at the door. Running a short cycle now and then keeps seals supple and parts moving, and it lets you catch a leak while you're standing there. Landlords can have us run and inspect an idle machine at turnover, before the new tenant discovers the problem with a full load of dishes.

In multi-story buildings a dishwasher leak doesn't stay in your kitchen. Water follows the floor under the cabinets and can show up in the ceiling of the unit below before you see anything. If you notice a damp toe kick, a soft floor or a musty smell, close the hot-water valve beneath the sink, which is safe to do, and stop using the machine. Tell your manager so they can check below, and book a repair; we'll write down where the leak came from. If the valve under your sink is seized, many buildings have a shutoff for each unit somewhere central, and it's worth learning where yours is.

With Everett's soft, slightly alkaline water, detergent goes further than the box suggests. Measure less detergent, top up the rinse-aid reservoir and rinse the filter often. Pods are convenient but can be too much for half loads. If your glasses already have a rainbow sheen or a cloud that vinegar won't remove, that's etching; it can't be reversed, but cutting the dose keeps it from getting worse. A detergent labeled for soft water, or simply less of an ordinary one, both work.
