What to check yourself
Step 1. Unplug for ten seconds and restart
LG asks for this first, and unusually for a reset it is worth doing here. The sensor is read continuously, and a single bad reading latches the code even after the condition has passed.
Step 2. Check the water supply is normal
A machine filling far more slowly than expected can produce this code rather than a fill error, because the level does not move when the sensor expects it to. Open both taps fully and check the inlet screens before assuming the sensor is at fault.
Step 3. Look for a suds problem
Heavy foam sits on top of the water and confuses a pressure sensor, which is measuring the weight of the column above it. If you have been generous with detergent, run a rinse and spin with none at all and see whether the code returns.
Step 4. Clear the filter and check the drain
A level that will not fall when the machine drains looks the same to the board as a sensor that will not report. Clean the pump filter and check the drain hose before booking anyone.
What a technician will look at
Described so you know what you are paying for, not as steps to repeat.
Pressure sensor, air hose or wiring
The sensor connects to the tub through a thin air hose, and that hose is the usual culprit rather than the sensor: it cracks, kinks behind the drum, or blocks with detergent sludge. A technician checks the hose first for exactly that reason.
When to call a technician
Once a reset, a good water supply and a clear drain have all been ruled out. This is one of the few codes where the diagnosis genuinely needs the back off the machine, so there is little point postponing it.
What the repair costs
| Repair | Part only | Fitted by a technician |
|---|---|---|
| Reset, clearing suds or a blocked filter | - | Free |
| Pressure sensor or air hose replacement | - | $150 to $350 |
| Control board replacement, in the rare case it is that | - | $250 to $500 |
A new machine of the same class runs $500 to $1,500. Once a quote passes about a third of that on an older appliance, the repair stops making sense.
Codes people confuse this with
Questions people ask
- Is the part expensive?
- The sensor itself is not, and the air hose costs very little. What you are paying for is the access: reaching either means opening the machine, so the labour dominates the bill. That also means it is worth asking the technician to check the hose before replacing the sensor.
- The code cleared after a reset. Is it fixed?
- Possibly, and it is reasonable to carry on and watch. If it comes back within a few washes the sensor or its hose is failing intermittently, and intermittent here tends to become permanent.
Which machines this applies to
Applies to
LG front load and WashTower machines, and the washer half of a washer dryer combo. Top load machines report level problems through fill and overfill codes instead.
