What error 7102 means

A wheel encoder reports wheel movement and rotation data to the mower. Code 7102 means that data is unavailable or unreliable, so this is different from being physically trapped.

Fix error 7102 in the safest order

  1. Stop the mower and record the code.
  2. Press STOP to clear 7102.
  3. If it remains, pull the mower off the charging station.
  4. Hold OK for three seconds to turn the H2 off.
  5. Turn the mower back on and allow it to initialize.
  6. Run a short level-ground test and contact support if the code returns.

Checks that prevent a repeat problem

  • Remove only loose external debris using the manual safety procedure.
  • Do not dismantle the wheel or encoder.
  • Test on firm, level lawn.
  • Note whether one wheel behaves differently.

How to verify the fix

Both wheels should respond normally and 7102 should not return during the supervised test.
