Bosch Dishwasher Repair in Northern Virginia, DC & Maryland

The Bosch dishwasher parts that fail most are the drain pump, the heat pump assembly with its built-in heater, the power module, the door latch, the door springs and cables, the door gasket, the inlet valve and the AquaStop hose. Filters, spray arms and rinse aid caps wear too, but they are simple swaps. We carry the common parts on the truck. Anything else is ordered by the model number on the sticker at the edge of the door; Bosch sells parts by model number through its own store, and the large US distributors stock most Bosch dishwasher parts and ship them the day they are ordered, so the technician comes back to fit it.

Three things set a Bosch apart from the dishwasher you may have had before, and each one changes how it fails.

There is no exposed heating element in the tub. Water is heated by an element inside the circulation pump, and drying is done by condensation. When a Bosch stops heating, the fault is in that pump assembly, and Bosch's E09 code names it a heat pump internal heater fault.

There is a float in the pan under the tub. Any water that reaches the pan lifts it, the machine locks out and pumps, and E15 shows. That is good protection for your floor, and for the neighbor's ceiling in the condo towers we cover under dishwasher repair in Bethesda, but it means a small leak anywhere underneath stops the whole machine.

The filter comes apart in three pieces in the sump, and the drain pump sits under a round cover next to it. E22 means the filter is blocked, E25 that the pump is blocked or its cover is loose, and E24 that the drain path is, which can be as simple as the hose loop shown on our dishwasher repair page; the Bosch dishwasher error codes guide lists the rest. Top-control models have no display on the front, which is why many of them shine a red dot on the floor while running; when that dot is off and the dishes are still wet, the cycle never finished.

The water across this area is hard. Hard water leaves minerals behind every time it is heated and dried, and a dishwasher heats and dries water several times a day.

On a Bosch that shows up in two places. Scale builds on the heater inside the pump, so it takes longer to reach temperature and eventually the element gives up. And a white haze settles on glasses, the same film our dishwasher repair in Alexandria page describes, which people often read as a washing fault when it is a water fault.

Rinse aid keeps the haze down, because it lets water run off the glass before it dries, and a dishwasher cleaner made for scale run once a month keeps the heater clean. If the haze wipes off with a cloth, the machine is fine. If the machine also runs long and the plates come out cold, the heater is the next thing we check.

Our visit fee is $89. The technician finds exactly what's wrong and gives you the full repair price at your home — no pressure. If you go ahead, the $89 counts toward the repair, and every repair has a 90-day warranty.

A built-in dishwasher has to come out from under the counter before most of it can be checked, so expect the technician to pull it, lay down floor protection first, and put shoe covers on at the door. You get the problem explained in plain English before anything is touched.

We book 2-hour arrival windows and the technician calls about 15 minutes before arriving. Someone answers the phone 24 hours a day, and same-day service is available most days. Payment is on completion, with the invoice sent by email or text.
