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 circulation pump is blocked. - In longer breaks between rinses (lasting weeks or months at a time), or when commissioning for the first time, the pump may be dry and stick or jam. - Risk of scalding. - Contact with hot water can cause scalding. - Take care with heated water. - Do not use excessively hot water (max. 165°F/75°C). - Pour 1 liter of hot water (max. 165°F/75°C) with 3 to 5 drops of rinse aid into the dishwasher interior. - Reinstall the filter combination. - Reinstall the lower spray arm. - There may be a technical condition. - For thorough and gentle cleaning of glasses, dishware, and cutlery, Miele recommends using the manufacturer’s products. ### Worth trying yourself, in this order - Remove the lower spray arm. - Remove the filter combination. - Leave the solution to soak for 5 minutes. - Ensure that the filter combination lies flat in the base of the wash cabinet. - Restart the program. - Repeat the process 2 to 3 times. - Turn off the dishwasher. - Wait a few seconds. - Turn the dishwasher back on. - Use the program selector to select the program you want. - Press the - Start/Stop ### 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](https://mielemiami.support/error-codes/) 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.
