(469) 638-3215Dishwasher not draining, leaking, leaving dishes dirty or showing an error code? ALAS Appliance Repair fixes built-in, drawer and portable dishwashers across Richardson, from Main Street and the US 75 corridor to Richardson Heights, Canyon Creek and Cottonwood Heights.
Business Profile

Many Richardson kitchens were not built around a dishwasher. In 1950s homes, common in Richardson Heights, the dishwasher was often added later in a space cut from the original base cabinets, so the drain, water supply and electrical connection were fitted in after the fact. When a replacement dishwasher leaks or drains slowly, the cause is sometimes an aging drain connection or a reused supply line rather than the machine itself, which is why we look at the whole installation.
Hard water is the other everyday factor. Mineral scale settles on spray arms, filters and heating elements, so cloudy glasses and a white film are frequent complaints around the city. Rinse aid, a clean filter and a periodic descaling cycle all help. When a cycle ends with standing water, look at the filter and the disposal, because a jammed disposal, or a newly installed one with its knockout plug still in place, will stop the dishwasher from draining.
Our Plano-based technicians cover Richardson from Main Street and the US 75, Belt Line, Campbell and Arapaho corridors to Richardson Heights, Canyon Creek, Cottonwood Heights, the Reservation, Duck Creek and Prairie Creek.

Canyon Creek homes mostly date from the late 1960s and 1970s, and many kitchens there have been remodeled since. A leak under the toe kick often comes from the door gasket, the pump seal or the supply connection, and in some remodels an older valve was kept behind the new unit. Turn off the water supply, lay down towels and book a diagnosis.
Yes. The Reservation in west Richardson has many new custom homes on rebuilt lots, and panel-ready or fully integrated dishwashers are common in kitchens like these, including Miele, Bosch and Thermador models. We remove and reinstall the unit with care to protect the custom panel and cabinetry. The model number on integrated units is usually stamped on the door’s top or side edge.
It is a common cause. Richardson buys its water from the North Texas Municipal Water District, and the dissolved minerals common to the region leave a film as droplets dry on glass. Rinse aid and regular descaling help a great deal. If glasses stay cloudy or gritty, the water may not be reaching the right temperature, or the spray arms may be clogged.
