Kenmore Washer F5 Error Code: Causes, Cost & Fix

What is the Kenmore Washer F5 error?#

F5 on a Kenmore washer is a water-temperature sensing fault: the NTC thermistor that reads incoming water temperature has failed or lost its connection, so the control can no longer confirm the water is heating to the selected setting. It is not urgent — the machine still runs — but wash quality suffers. The very first thing I check is whether the hot supply is actually connected and open, because on these Whirlpool-platform (110-series) Kenmores an F5 often shows up when only the cold line is hooked to the machine.

F5 on a Kenmore Washer: likely causes and repair cost#

On a Kenmore Washer, the F5 code signals: water temperature sensing error.

Typical professional repair: $75–$200 · Difficulty: moderate · usually a technician job

Symptoms that often accompany F5: Cold water wash despite hot setting; Water temperature inconsistent; Cycle takes longer than normal

Technician diagnostic sequence for F5:

1. Verify hot water supply valve is open and connected
2. Locate NTC thermistor on the outer tub — measure resistance (~10K ohms at room temp)
3. Check wiring from thermistor to control board for damage or loose connectors
4. If thermistor reads open or near zero, replace the sensor

Parts a technician may check or replace: NTC temperature sensor; water inlet valve

Field note: Applies to models starting with 110.xxxxx (Whirlpool platform). F5 can appear when only cold water supply is connected — check hot valve before replacing sensor.

How to troubleshoot the F5 error yourself#

There is exactly one owner check worth doing before this becomes a technician job. Reach behind the washer and confirm the hot water valve is fully open and its hose is connected — as the table above notes, F5 can appear simply because the hot supply is missing, so never replace a part until you have ruled that out. Then run a warm or hot cycle and feel whether the inlet water is genuinely warm.

If the supply is fine and the code returns, hand it off. A technician locates the NTC thermistor on the outer tub, meters its resistance against the roughly 10K ohms it should read at room temperature, and inspects the wiring back to the control board for damage or a loose plug. Tub access and metering put the actual sensor swap out of DIY range, so stop at the supply check.

Is the Kenmore Washer F5 error worth fixing?#

This is one of the cheaper Kenmore washer faults to fix. The table above puts a professional repair at $75 to $200, usually a temperature sensor and occasionally the water inlet valve, and because your machine is a Whirlpool-platform build those parts are common and inexpensive. Against the cost of a new washer that is a small outlay, so on any washer that is otherwise sound the F5 repair is clearly worth doing. I only steer owners toward replacement when the machine is already old and piling up other failures.

Kenmore Washer F5: frequently asked questions#

What does the F5 error mean on a Kenmore washer?#

It means the water-temperature sensor — an NTC thermistor on the outer tub — has failed or lost connection, so the washer cannot verify the water temperature. On these Whirlpool-platform Kenmores it usually points at the sensor, but check that the hot supply is connected first.

Is it safe to keep using a Kenmore washer showing F5?#

It is safe to run, but results suffer because the machine cannot regulate temperature and may wash cold even on a hot setting. Confirm the hot supply is connected, then have the sensor checked when convenient.

Can I clear the F5 error myself, or do I need a technician?#

You can clear it if the cause is a disconnected or closed hot valve — open it and rerun a hot cycle. If the thermistor itself has failed, a technician should meter and replace it.

How much does it cost to repair F5 on a Kenmore washer?#

The table above lists $75 to $200 for a professional repair, which covers the NTC temperature sensor and, if needed, the water inlet valve.

Which parts usually fail when a washer throws F5?#

The NTC temperature sensor on the outer tub is the most common failure. A disconnected hot supply or damaged sensor wiring produces the same code without any part being bad.

Is a Kenmore washer with F5 worth repairing?#

Yes. As a Whirlpool-platform machine the parts are cheap and common, so a $75 to $200 sensor repair is easily worth it on a washer in good shape.

Why does a failed NTC thermistor trigger F5?#

The control reads water temperature through the thermistor, whose resistance changes with heat. When it reads open or shorted instead of the expected value near 10K ohms, the board cannot trust the temperature and posts F5.
