Miele dishwasher error code F13

What Miele publishes for it

On a Miele dishwasher, the manufacturer publishes this for the water inlet is blocked or restricted. That sentence is Miele's own, read off its published support page for this condition rather than worked out from the outside. Everything below it — what the condition covers and what is worth doing first — is ours, written from what this equipment does in Miami kitchens.

What this block of conditions is about

The largest block in this archive, and the one with the most conditions an owner can clear without a visit — the water side of a Miele dishwasher reports itself in detail, and several of these numbers mean a filter, a hose or a tap rather than a part.

What it covers

What a published cause names is a circuit rather than a component, which is the single most useful thing to know before anybody orders a part. This one covers:

• The faucet is not open.
• The inlet filter is soiled.
• Risk of electric shock from voltage.
• The plastic housing of the water connection contains an electrical valve.
• The housing must not be dipped in water.
• Unscrew the water intake valve.
• Using combination or needle-nose pliers, take hold of the plastic filter bar and remove the plastic filter.
• Re-insert the plastic filter and the seal into the screw connection of the water intake valve. Ensure that the plastic filter and the seal are seated correctly.
• Screw the screw connection of the water intake valve securely onto the faucet.
• Slowly open the faucet.
• If water drips out, tighten the connection.
• The plastic filter
• Be put back in place after cleaning.
• The water inlet hose is kinked.
• Monitor these points for a while afterward, as the plastic may weaken and the material may tear.
• In the event of any damage, the water inlet hose must be replaced.
• The flow pressure at the water connection is lower than 7.25 psi (0.5 bar).
• Contact the facility manager or a plumber.

Worth trying yourself, in this order

1. Turn on the faucet.
2. Clean the inlet filter:
3. Turn off the dishwasher.
4. Disconnect the dishwasher’s electrical plug.
5. Close the faucet.
6. Remove the seal from the screw connection.
7. Rinse the plastic filter under running water.
8. Remove any kinks or loops from the water inlet hose.

Then what

Start with the water, because on a Miele dishwasher this is where the owner's half of the diagnosis lives. The tap, the inlet filter, the hose and the drain account for most of the conditions the machine can report, and all four are reachable without tools. South Florida's water leaves scale in the inlet filter faster than the manual expects, so a filter that was clean a year ago is not clean now.

Miele publishes this one for the dishwashers. The full Miele archive has the other conditions, searchable, and on this make the same number appears on more than one machine roughly a third of the time, so the appliance above is part of the answer. We repair this equipment across Miami-Dade, Broward and Palm Beach.
