What this one means
The heat pump cannot move water through itself. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
What the code covers
A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:
- Scale
- Debris carried down from the filter
- The pump itself
What to try yourself
- Descale an empty machine and clean the filter, then run a hot cycle
Then what
If it clears and returns within a few weeks, the pump is failing rather than dirty.
