Err 2

How to Fix It

1. Power off and lift out.

   Disconnect the power supply.
   Lift the cleaner by the handle.
   Drain over the pool for a minute.

2. Inspect the tracks.

   Flip the cleaner over.
   Look at both tracks.
   A track that came off the drive wheel is the most common Err 2 cause.
   Reseat the track over the wheel — stretch it gently with two thumbs and pop it back into place.

3. Pull off the tracks completely.

   Tracks slide off the drive wheels with a firm pull.
   Once off, you can see the drive shaft clearly.
   Look for hair or fibres wrapped tightly around the shaft — very common after the cleaner has been in pools shared with long-haired bathers.

4. Clear debris from the shaft.

   Use sharp scissors to cut through the wrapped material — do not pull, that can damage the seal.
   Once cut, unwind and remove every piece.
   Wipe the shaft with a clean cloth before reassembling.

5. Check track tension.

   Pull the track between drive and idler wheels — about 1 cm of give is normal.
   Loose track that slides off easily = stretched = needs replacement.
   Genuine Maytronics tracks are 30-80 USD per pair.

6. Test the drive motor.

   Reassemble the tracks.
   Place the cleaner on a smooth surface (not in the pool).
   Power on.
   Tracks should rotate.
   One side fails to turn = drive motor on that side has failed; both sides fail = harness or power supply issue.

7. Contact Maytronics for motor service.

   If hair is cleared and tracks are good but Err 2 persists, the drive motor has failed.
   Out-of-warranty drive motor replacement is 150-300 USD.
   This is generally not a DIY repair — the motor sits inside a sealed housing.
