Electrolux 250SD Not filling with water whatever cycle is selected.

indicates no water flow from taps or the water solenoid is faulty and not opening the valve

If you have checked all the above then may be the inlet valve has a fault.

hmm sounds like as if any water sensors arent working as they should inside the washing machine's basket or the diagnostic board isnt getting the right info from its sensors in the washing machine's wash tub

Thank you for your post, friend!
I see that your Electrolux washer won't fill during the cycle and makes a clicking sound. This clicking sound could come from either the motor or the water valve. In order to locate which component could be causing the issue you may need to disassemble your washer. I would recommend having a professional technician out to properly disassemble the washer to prevent any personal injuries or future issues. I hope this information is helpful to you. -Matt

Your drain hose is pushed too far down into the drain so when you select the larger load sizes the water is being siphoned out as it goes in due to the pressure differential.

front loader washers fill accourding to how big the load size is on all front load washers.There should be no water above the center with a full load.If it is spinnig out and draining then it is working properly:)

Is your drain pump constantly running? If it isn't, check the standpipe (drain pipe) and make sure you don't have your drain hose shoved down in the pipe too far or the top sealed off. The stand pipe needs an air gap to properly drain, or it can siphon water from the wash tub. Symptom: Washer continually tries to fill or slow fills, but water won't stay in wash tub. Double check your drain line to be sure. It could be a simple fix.
