Hotpoint dishwasher error codes

13 codes that Hotpoint publishes for its dishwashers, each with what it means, the likely cause, what you can safely check and when to call a technician. Tap your code:

Switch off and unplug before checking. Anything electrical, anything to do with gas, and any water leak at the mains: call a technician. Codes that need one are marked Technician.

Read this first

Hotpoint dishwashers show an F code on the display, or — on models without one — a pattern of flashing LEDs that Hotpoint's page maps to the same F code. Every code below is on Hotpoint UK's own error-code page. Whirlpool and Indesit dishwashers come from the same group and often use similar codes, but the source here is Hotpoint's: check your own manual before relying on it for another brand.
