If water does not enter the Electrolux ELFW7637 or enters slowly, Electrolux's checklist lists: the water supply is not adequate in the area (check another faucet in the house and wait until pressure increases), the supply faucets are not completely open (fully open both), water is being used elsewhere in the house (pressure must be at least 30 psi or 260 kPa, so avoid running water elsewhere while the washer fills), the inlet hoses are kinked (straighten them) and the inlet screens are plugged (remove the hoses from the inlets and clean the screens). The reversed-hose alarm HO SE and the hot water setting (at least 120 F) also matter. Electrolux's Laundry Water Supply Guide covers the supply.
Differential
Likely causes of “Electrolux ELFW7637 front-load washer will not fill with water or fills too slowly”, and how to tell them apart
- 1
Faucets not fully open or a weak supply
What separates it There is a slow or absent fill because the faucets are not fully open or the supply is weak
How to confirm Fully open both faucets and check other faucets
- 2
Water used elsewhere in the house
What separates it The pressure is below 30 psi because water is being used elsewhere in the house
How to confirm Avoid using water elsewhere while the washer fills
- 3
Kinked inlet hoses
What separates it There is a trickle because the inlet hoses are kinked
How to confirm Straighten the hoses, and try the fill again
- 4
Plugged inlet screens
What separates it There is a slow fill because the inlet screens are plugged
How to confirm Remove the hoses, and clean the screens well
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the faucets are fully open
- The pressure at other faucets in the home
Try in this order
0 of 5 completedOpen the faucets
ReversibleOpen the faucets, and make sure that both are fully open, and then test again to see whether it helped.
Straighten the hoses, and try the fill again
ReversibleStraighten the hoses, and make sure that there are no kinks, and then test again to see whether it helped.
Clean the screens
ReversibleClean the screens, by removing the hoses from the inlets and cleaning the screens, and then test again to see whether it helped.
Check pressure
ReversibleCheck the pressure, which needs 30 psi minimum, with no water used elsewhere while filling.
Check the hose connections
ReversibleCheck the hose connections, with hot to hot and cold to cold, and then test again to see whether it helped.
Model-specific
What is true of this model and not of its siblings
- Hot water and temperatures
- Electrolux's checklist says warm or hot water that is not hot enough may come from a hot water heater set too low or at a distance from the washer: measure the hot water temperature at a nearby faucet with a thermometer; it should be at least 120 F (49 C). Hot water used elsewhere before or during the wash can leave too little, and if the problem persists the hot water system may not support more than one use at a time.
- Incorrect temperatures
- Incorrect wash and rinse temperatures come from hot and cold hoses connected to the wrong faucets, and the LED alerts this condition with the HOSE alarm. Connect the hot water hose to the hot water faucet and the cold hose to the cold faucet, and check the connections again after any plumbing work.

Stop boundary
When this stops being a self-service repair
- !If the fill stays slow after the screens are cleaned and pressure is good, contact Electrolux service
- !If hoses leak or hammer, shut off the water and call a plumber

At least 30 psi (260 kPa).
What if the hot water is not hot?+
The heater should deliver at least 120 F; hot water used elsewhere can leave too little.
What is the reversed-hose alarm?+
HO then SE on the LED.
Does the door matter?+
The unit will not operate with the door open.
Where is the water supply guide?+
