If not then replace the temperature sensor because it's defective. If resistance is okay, check the wire harness connections between the temperature sensor and the main electronic control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire harness connections are okay then you'll usually need to replace the main electronic control board Clearing a filter or straightening a hose is within reach of anyone; anything behind a panel means mains electricity and water together — that is a job for a technician.
