Insignia Washer E1 Error Code: What It Means and How to Fix It

Last updated: October 5, 2026 · Codes covered: E1 · Sources

An E1 code on an Insignia top-load washer means it didn't fill with enough water, or didn't reach the right water level, within the time its controls allow. Usually the fix is simple and free: a faucet that isn't fully open, a kinked hose, or clogged filter screens in the hoses. If the water supply is fine and E1 keeps coming back, a part like the inlet valve may have failed.

What the E1 code means

Insignia's user guide for the top-load washer NS-WMT41WA5 describes E1 as: "When your washer fails to fill sufficiently within five minutes, or the water level fails to reach a certain level within a specified time."

That time limit is a safety feature. Insignia says it's built in to prevent flooding if a hose comes loose, so if water comes in too slowly, the washer turns off and reports an error.

Insignia's fixes for E1 are to make sure the lid isn't open, make sure water isn't leaking, work through the guide's "No water or not enough water" checks, and then contact Insignia Customer Care.

Two things that are normal, not a fault:

• A short delay before filling. On automatic cycles, the washer tumbles the dry clothes for up to about a minute to sense the load, then fills.
• Low water. It's a high-efficiency washer, so Insignia says low water levels are normal, even with clothes sticking out.

Look-alike codes on the same washer:

• E2: the washer took more than 10 minutes to drain.
• F8: water level sensor failed. Insignia says to contact Customer Care.

Codes vary by model, and this guide covers the NS-WMT41WA5. If yours is different, check your own user guide's error code table.

Likely causes (most common first)

1. Faucets not fully open. Both the hot and cold faucets need to be turned on all the way.
2. Kinked or twisted inlet hoses.
3. Clogged hose filter screens. On this washer the filters sit in the faucet end of each inlet hose, in place of the rubber washers.
4. Low water pressure. Insignia calls for 14 to 116 psi (100 to 800 kPa). Below 14 psi, the washer may take longer to fill than its controls allow.
5. Only one hose connected. Insignia says to connect both the hot and cold faucets, and that an error code could occur if either isn't connected. If you don't use hot water, the hot intake needs a cap (sold separately) and you have to select Tap Cold.
6. Lid not fully closed. Insignia lists this first among its E1 checks.
7. A water leak, so the tub loses water while it's filling.
8. Frozen lines in an unheated space.
9. Inlet valve, water level sensor or control problem. If the supply checks out, the problem is likely inside the washer.

How to fix it, step by step

Do these in order. Try a cycle again after each step.

1. Close the lid firmly, turn the washer off and on with Power, and restart the cycle. On automatic cycles, wait out the load-sensing tumble before deciding it isn't filling.
2. Open both faucets all the way. Leave them fully open while the washer runs.
3. Straighten the hoses. Pull the washer out gently and check for kinks or twists.
4. Check both hoses are connected. Hot faucet to the hot intake, cold to cold. If you only use cold, make sure the hot intake is capped and you've selected Tap Cold.
5. Look for leaks at the hose fittings and under the washer. If water is getting into the washer anywhere other than the tub, unplug it and contact Insignia service, as the guide advises.
6. Check the water flow.
   • Unplug the washer and turn both faucets off.
   • Disconnect the hoses from the washer, with a towel ready.
   • Put the loose ends in a bucket and turn the faucets on.
   • A strong stream is good. A trickle points to the plumbing, faucet or hose.
7. Clean the hose filter screens.
   • Keep the washer unplugged and the faucets off.
   • Unscrew each hose from its faucet. The filter sits in the hose fitting at the faucet end.
   • Rinse the filter under running water until it's clear.
   • Refit it. Hand-tighten the fitting until snug, then give it two-thirds of a turn more with pliers or a wrench, as Insignia instructs. No tape or sealant.
   • Open the faucets slowly and check for leaks.
8. Check your water pressure. If other taps are weak too, or you're on a well, have the pressure checked against Insignia's 14 to 116 psi range.
9. Check for frozen lines in a garage or unheated space, and let everything thaw before using it.
10. Suspect the inlet valve. If water flows well and the filters are clean but E1 keeps coming back, the inlet valve (or the water level sensor or control) is the likely cause. See "Test the part" below, or call for service.

Test the part

If the water supply is fine, the likeliest failed part is the water inlet valve, on the back of the washer where the hoses connect. Each water line has a small coil (solenoid) that opens the valve, and you can check the coils with a multimeter, with the washer unplugged.

1. Unplug the washer and turn off both faucets. Insignia warns that the electrical valve, motor and drain pump are intentionally not grounded and may present a shock risk during servicing. Don't touch them while it's plugged in.
2. Disconnect the hoses at the back of the washer, with towels down.
3. Reach the valve's wire connections. This usually means removing a rear or top panel. Access varies by model and Insignia doesn't publish the steps, so if there's no clear way in, stop here. Watch for sharp edges.
4. Photograph and label the wires, then pull each connector off by its housing, never by the wire.
5. Check each coil. Set the meter to its lowest ohms (Ω) range and touch one probe to each terminal of a coil.
   • Some resistance (a reading) means the coil has continuity.
   • Infinity or "OL" means the coil is open and the valve needs replacing.
   • Insignia doesn't publish a resistance value, and PartSelect notes readings vary by brand and model. Compare against your model's tech sheet if it has one. A coil that reads very differently from the other is also suspect.
6. Reconnect everything exactly as in your photos before you restore water and power.

A valve can pass this test and still be stuck shut inside. If the coils have continuity and E1 keeps coming back, stop and call for service. Next come live-voltage, water level sensor and control board checks, and those aren't DIY jobs.

Safety notes

When to call a pro

Contact Insignia Customer Care or a qualified appliance technician if:

• E1 keeps coming back after every step above.
• Water flows strongly from both hoses but the washer still won't fill.
• The washer doesn't stop filling. Insignia notes that very low pressure can keep the valve from shutting off completely.
• You see a leaking inlet valve, damaged wiring, or water inside the cabinet.
• The washer shows F8 (water level sensor failed).
• Your washer is still under warranty. Insignia's limited warranty runs one year from purchase (or delivery, if later), and its terms exclude damage from repairs by anyone Insignia hasn't authorized. Contact Insignia before you take panels off.

You can reach Insignia support at 1-877-467-4289 (U.S. and Canada), the number listed on Best Buy's Insignia support page and in the user guide.
