Miele dishwasher error code F52

What Miele publishes for it

On a Miele dishwasher, the manufacturer publishes this for excess quantity of cleaning agent/rinse aid dispensed. 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:

• Excess quantity of cleaning agent/rinse aid dispensed.
• A sensor has detected too much foam inside the appliance. The wash program has been interrupted.
• To remove the message, set the program selector to
• Or, if you are using light-touch switches, press and hold
• For around 5 seconds.
• If you are using cleaning agent tabs that already contain rinse aid, select the combination tab function (if available).
• Do not use cleaning agent tabs with the Express 40°C program.
• For thorough and gentle cleaning of glasses, dishware, and cutlery, Miele recommends using the manufacturer's products.

Worth trying yourself, in this order

1. Start/Stop
2. Switch your appliance off and back on again.

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.
