Clicking but not starting cycle,

test the door switch for continuity ,good luck APPLIANCES R EN

see this causes and fix it. God bless you
Lid Switch Assembly If the washer stops mid cycle the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Door Lock Motor and Switch Assembly If the washer stops mid cycle the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.
Water Inlet Valve If the washer stops mid cycle the water inlet valve cold water side may have failed. Most washers have a cold water rinse and so if they can't fill with cold water they just sit indefinitely waiting for the cold water to enter. If there is cold water to the water inlet valve and the cold water works in other parts of the cycle - or to make warm water - the valve is not the problem.

Main Control Board If the washer stops mid-cycle the main control board might be defective. This is not common. Check other causes first such as the lid or door switch and other components.

Timer If the washer stops mid cycle the timer might be defective. This part is often misdiagnosed, check other components before replacing this timer.

Be very careful, it sounds like an electrical failure, were the machine has cut out to protect you and itself. You need an expert there and quickly. Water and electric are a bad mix and more house fires are caused by washers than most other appliances.

you need a water valve if the overfill float is not malfunctioning

Do you ever hear the fill solenoid click on to begin the filling. That is the first thing that has to occur. The water supply generally connects right to that solenoid. Ohm out the solenoid coil. ( breaker power off)

The water level sensor is faulty and so it does not switch even with water level coming to the set level. Unless the water level switch is triggered the water inflow will not stop because the inlet valve will not cut off.Remove the water level sensor and check if the diaphragm is working , if not it must be replaced.

Probably needs new carbon brushes in motor.

The amps on the unit have probably died. Did they replace it for you? I'm becoming alarmed at the number of units just dying for an $800 piece of equipment.

if this is a two piece agitator,it should behave like a ratchet turn freely clockwise and catch counter clockwise if it doesn't catch the agitator "dogs " are shot this is a verry inexpencive repair

Sounds like a bad thermistor
