+===== Description =====
-TBD
+==== Lost position ====
+If the robot does not position correctly during washing it could be due to a number of reasons:
+  * Lost positions between restarts
+  * Moved or faulty zero position sensors
+  * Setting boom zero position not in bottom (ie. accidentally set zero position when it is stuck)
+Lost positions will show when robot parks incorrectly between washing programs or when it does not wash where it should. [[:troubleshooting:no_alarm:robot_positions_incorrect|Read more about possible explanations for incorrect positioning here]].
+==== Lost homing ====
+If the homing is lost the robot will show an alarm ([[:troubleshooting:alarm:homing_needed|]]) when trying to start an automatic wash. It will also show as red circles on the detailed manual screen. If your EVO Cleaner needs a new homing, see [[:service:service_instructions:homing_instruction|this Homing instruction.]]
+Lost homing can also mean lost parking positions, which will show when robot parks incorrectly between washing programs.
+==== Lost clock ====
+The clock is seen in the top right corner on the start screen. Date is seen on the [[:user_manuals:screens#settings_screen|Settings screen]]. A lost clock sets the date and time to 1996-01-01 00:00.
+===== Troubleshooting =====
+  * Redo the [[:service:service_instructions:homing_instruction|initialization]]
+  * Check that battery connectors are firmly attached, ie. no loose contact, and that the cables are not damaged. A panel that is restarted very frequently can loose positions.
+  * Check for damaged panel, especially for holes in the overlay and cracks in the housing. Water ingress can lead to lost data.
+  * Always make sure the robot is turned off before replacing batteries
+  * Contact Service in order to check stored parking positions
+  * Contact Service in order to check operators panel's [[:parts:panel#backup_battery|backup battery]] status
