A Miele dishwasher reports which end of that it stopped at, which is why this repair starts with reading rather than with dismantling. ### What actually goes wrong - **A tap that is not fully open**, usually after work under the sink. - **The inlet filter**, loaded with scale in water harder than the machine assumes. - **A kinked or looped hose** behind a machine that has been pushed back in. - **The drain hose loop**, which lets the sink drain back into the tub when it is lost. - **The drain pump or the inlet valve**, which is where this becomes a part rather than a check. ### Why we ask about the sink Because a good share of dishwasher drain calls are about the plumbing the dishwasher is connected to rather than the dishwasher. A new disposal with its plug still in, a sink that drains slowly on its own, a hose run under a cabinet floor — all of them present as an appliance condition. What this involves The tap, the inlet filter and the hose checked before any part Drain path proved from the tub to the standpipe Flow pressure measured, not assumed Read what the machine stopped at Filling and draining are separate conditions with separate numbers on this make, and knowing which one it is halves the search before anybody opens anything. The four free checks, in order Is the tap fully open, is the inlet filter at the screw connection clear, is the hose kinked or looped behind the machine, and is the drain hose still in its high loop. The manufacturer publishes all four and between them they end a real share of these calls. Measure the flow pressure The maker names a minimum of 7.25 psi and names low pressure as a cause. It is measured rather than guessed, because a machine on a shared line behind other fixtures can be below it only at certain times of day. Then the parts The inlet valve, the drain pump, and the pressure system that tells the machine how much water it has. Proved before ordered.

A new disposal with its plug still in, a sink that drains slowly on its own, a hose run under a cabinet floor — all of them present as an appliance condition. ### Where exactly is this inlet filter everyone mentions? Inside the screw connection where the hose meets the tap, not inside the machine. Close the tap and unplug the appliance first — the plastic housing there contains an electrical valve and must not be dipped in water. The filter comes out with needle-nose pliers, rinses under running water, and goes back with its seal. ### It drains if I run it again, but not every time. Intermittent is usually the path rather than the pump: a drain hose that has lost its high loop, a disposal plug that was never knocked out on a new installation, or filters in the base of the tub that are partly loaded. A pump that is failing tends to fail the same way every cycle. ### Could hard water really be the cause? For the inlet side, frequently. The interval the machine assumes for that filter was written for softer water than Miami-Dade, Broward or Palm Beach supply, so it blocks earlier than anybody expects and nobody has ever cleaned it. --- **[Read full article: Dishwasher drain & fill repair](https://mielemiami.support/services/dishwasher-drain-and-fill-repair/)**
