Probable Faulty Locations
1)Coolant level
2)Float switch position
3)Malfunction of float switch
For code 36->The coolant filter is clogged.
Malfunction of high-level switch.

Measures to Take
1)Replenish coolant.
2)Check the float switch.
3)Change the float switch.
For code 36->Change the coolant filter.
Change the high-level switch.
