This is a hard alarm.

The hose reel has stuck and the robot cannot disentangle it.

• Check that the hose spreader is working
  • Check that the hose spreader stroke is centered
  • Check that the hose is evenly distributed on the reel
• Check that the hose reel motor is working and that it has not lost power
• Check that the hose reel drive sprockets are aligned and that the chain is tightened adequately
• Check that the hose is not caught in the surroundings or slats and that it is laying centered in the aisle
• Check that the hose reel is moving freely and that the reel bearings' friction hasn't increased
• Check that the hose is tightly wound on the reel
  • Hose grows on reel
• Check that there are no leakages (eg. reel swivel) causing the pressure washer to build up pressure repeatedly
