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.

Dishwasher detergent dispenser won't open (detergent left in the cup)

First rule out blocking dishes, caked detergent and an unfinished cycle. Then test the dispenser actuator (a wax motor or bimetal/solenoid on most units) for an open circuit, and check whether the control sends 120 V to it during the wash. A cup that opens but leaves detergent behind is a wash problem, not a dispenser problem.

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.

Dishwasher completely dead: no lights, no response (supply, door switch, thermal fuse)

Prove supply voltage at the junction box with a meter before blaming any part. Then check the door switch circuit and, on units that have one, the one-time thermal fuse near the control. Replace the control board only after these pass.
