 ===== Description =====
-The hose spreader spreads the hose so its evenly distributed on the hose reel. For various reasons, it happens that it stops. Here we go through different errors and the solutions to these problems.
+The robots hose spreader distributes the hose equally on to the hose reel. It could happened that it stops, which could cause [[:troubleshooting:alarm:hose_reel_stuck|"hose reel stuck" alarm.]] Here we go through different errors and the solutions to these problems.
   - Start the robot. Lower the det transport wheel so the robot stands with the rear wheels in the air.
       - Double click on the rear wheel of the robot, this will make the rear wheels lock the drive backwards, the hose reel will try to roll up the hose and the hose spreader will start to swing in its motion. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
   - If the hose spreader doesn't move, wait for at least 2 minutes, the hose spreader can stand still and wait at its turning point before turning. If it does not start, then the troubleshooting begins in the hose spreader box. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
-  - The lid of the box is mounted with 4 screws, one screw is in a tight spot but can be removed with a small flat chisel. Remove the grey side panel of the robot to make more space while you work. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
+  - The lid of the box is mounted with 4 screws, one screw is a bit tricky to remove but can be removed with a small flat chisel. Remove the grey plastic side of the robot to make more space while you work. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
   - Due to vibrations in the robot, the connectors may jump of its place. To fix this we put a small amount of MS Polymer on the connector to hold it in place. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
-  - Check the connector if you have power from the circuit board. Measure between pin 1 and pin 2, it should be 24 V when the spreader motor is running. When the motor is going the opposite direction, it will have 24V between pin 1 and pin 3 too. Measure the cables for the small electric motor as well, to check if the circuit board is broken. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
+  - Check the connector if you have power from the circuit board. Check with a voltmeter, it is 24V between pin 1 and pin 2 when the wheels are rotating and the hose spreader motor is running in a given direction. If you change direction on the wheels (on the manual screen) or the spreader switch direction at the turning point the hose spreader motor will go the other direction, then it is 24V between pin 1 and pin 3 instead. Measure the cables for the small electric motor as well, to check if the circuit board is broken. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
   - Once you have measured and checked if the hose spreader motor have power, you must check if moisture/water has entered the box. It may happen that water enters through the plug, cable entry or entrance to the hose spreader rod. Here you can see how water has flowed in from different entrances. \\ <font inherit/inherit;;#ffffff;;inherit>.</font>
   - You must seal all three entrences if this isn't done already.
