Field pattern: Bosch dishwasher E24 / E25 (filter, pump cover and impeller before a new drain pump)

E24 points to a drain problem and E25 to a blocked drain pump or a pump cover that is loose or missing. Most of these are cleared from inside the tub: filter, the clip-on pump cover under it, and a jammed impeller (glass, pits, thread wrapped on the shaft). The wrong turn is ordering a drain pump or board before opening the pump cover and checking the drain hose and disposal connection.

Gritty or sandy residue on dishes after washing

Grit is usually redeposited soil: a clogged filter, a drain that cannot clear (air gap, disposer, hose) or detergent that did not dissolve. Hard water causes white film rather than grit. Work from the filter outward, then check the drain path and the wash motor.

Field pattern: Miele dishwasher F11 drain fault (non-return valve seating, filter and pump cover before a pump)

Miele F11 is a drain fault. On many older series the non-return valve in the sump is either blocked (pit, glass) or was put back crooked after cleaning; on 2019-on G 5000 / G 7000 series the drain pump cover not being locked is the usual cause. The wrong turn is pulling the unit to replace the drain pump before reseating the valve or cover and checking the drain hose.
