Re: Electrolux ESL6115
Basic’s need to be checked first. You need to open up sump hoses and pump,could be something floating around which is occasionally causing problems.Is it connected directly to the sink outlet,these get gunged up.
Pump itself may be worn ,modern ones (syncronus motors) can run in both directions so sometimes will jam sometimes not.
Check for pump impellor shaft not being looose in bearings and look for water in the motor shaft housing.
