Bonaire fault code E02
Water level fault (evap).
What E02 actually means
Water level fault. The unit cannot get the reservoir to the level it wants, either because water is not coming in or because the float is not reading correctly.
What causes it
- Water inlet solenoid blocked or failed
- Float valve stuck, often with scale or sediment
- Water supply restricted or turned off
- Reservoir draining faster than it fills, which means a leak or a stuck dump valve
- Sediment build-up after a season without a clean
Most likely first. That order is from what we actually find on site, not from the manual.
Safe to check yourself
No tools, no covers off, nothing to do with gas, refrigerant or wiring.
- Check the water isolation tap to the unit is fully open
- Check other taps in the house run at normal pressure
What we check on site
So you know what you’re paying for.
- Inlet solenoid operation and strainer
- Float valve inspection and clean
- Dump valve operation
- Reservoir clean and sediment removal
- Fill and drain cycle test
Can you keep using it?
It will run and it will not cool properly. No safety issue, but running an evap with the pads only partly wet puts uneven load on the pads and shortens their life.
What the fix usually involves
Usually a clean: reservoir, float and strainer. This is the job a pre-summer service does before it becomes a call-out in February.
Is it worth fixing?
That depends almost entirely on how old the unit is. Past about ten years on hot water and gas heating, and twelve on aircon, a significant repair usually costs more per remaining year than a replacement does — and it’s the same point at which the VEU rebate is worth the most, because old inefficient appliances are exactly what the scheme pays to remove. If yours is young and the fault is a component, we’ll fix it and say so.
