Bosch SMS25EW00GB Serie 2 dishwasher: specs, common faults and error codes

The SMS25EW00GB is a full-size, 60 cm freestanding dishwasher from Bosch’s entry-level Serie 2 range, part of the SilencePlus family. It is a straightforward machine: a clear programme dial, a small display for remaining time and delay start, and capacity for 13 place settings. That simplicity is a large part of its appeal — there is very little electronics to go wrong.

Common problems and what they mean

E15 – water in the base

Bosch dishwashers have a float switch in the base tray. If water collects there, the machine stops and shows E15, and the drain pump may run continuously. Common causes are a leaking door seal, a loose spray-arm or hose connection, or simply too much foaming detergent. Switch off at the wall, tilt the machine slightly back to let the water drain from the tray, and look for the source before using it again. A recurring E15 usually needs the base opened by a technician.

E24 and E25 – drainage faults

E24 points to a drain blockage: a clogged filter, a kinked drain hose or a blocked connection under the sink. E25 means the drain pump itself is obstructed — often by broken glass, a cherry stone or a label from a jar. After removing and rinsing the filter, the pump cover underneath can be lifted out so the impeller can be checked by hand (with the machine unplugged).

Dishes not drying

Serie 2 machines rely on condensation drying, so plastics often stay damp. Using rinse aid and opening the door a little at the end of the cycle makes a clear difference.

Maintenance that prevents most call-outs

1. Rinse the filter combination every one to two weeks.
2. Keep the salt and rinse-aid reservoirs topped up, especially in hard-water areas.
3. Run a hot, empty cycle with a dishwasher cleaner every month.
4. Check the spray arms for blocked nozzles a few times a year.

Verdict

The SMS25EW00GB is a good choice for anyone who wants a quiet, dependable dishwasher without paying for features they will not use. Most faults owners report are drainage-related and can be prevented with regular filter cleaning; the repair-or-replace question usually only arises when a pump, heater or control board fails after many years of use. Those parts are shared across many Bosch dishwashers, so a technician who specializes in Bosch appliance repair can usually source them quickly.
