Fix Kenmore Washer Temperature Not Right

Quick Answer: Why Your Kenmore Washer Water Temperature Is Wrong#

Most likely: a fill problem on the hot side — a failed hot inlet-valve solenoid, a clogged inlet screen, or simply a house water heater that is not delivering. The critical fact most owners miss is that all 110-series and most 417-series Kenmore washers have no internal heater; they take whatever hot and cold your household plumbing supplies. So "not hot enough" usually starts at the tap, not the machine. Only 796-series (LG) and some 417-series models heat water at all, and even then only for Sanitize or Allergen cycles.

Likely Causes at a Glance#

Walking Through the Diagnosis#

Because most of these machines make no heat of their own, start at the house supply. Run hot water at the nearest sink to confirm the water heater actually delivers, then check the fill hoses — hot to hot and cold to cold. A surprising share of "too hot on cold" complaints are simply crossed hoses at the wall.

Next, pull the inlet hoses and inspect the screens for mineral buildup; in Sacramento and Bay Area cities where hardness runs 10-17 grains per gallon, a partly blocked screen is a common cause of lukewarm fills. With the screens clear, meter the inlet-valve solenoids — a healthy coil reads roughly 500-1,500 ohms, and a dead hot-side coil means only cold water enters no matter what the control board commands. That is a valve replacement, not a control-board job.

On 796 (LG) or 417 (Electrolux) models that heat for Sanitize, an under-temperature cycle points at the heater or its sensor. The thermistor is an NTC type reading about 50,000 ohms at room temperature; if it reads far from that, the board gets bad temperature data. Confirm the internal heater element has continuity before condemning the board.

Repair or Replace? The Short Version#

Temperature faults are almost always a valve, a screen, or a sensor — low-cost parts and adjustments that keep any repair far below the half-rule line. On the many heater-less models, the "fix" is often free: raise the water heater setting and purge the line before a wash. If metering a dual solenoid valve is not your thing, our technicians carry the OEM parts and diagnose it in one visit — get started.

Frequently Asked Questions#

My Kenmore 110 washer water is never hot enough — can I add a heater?#

No — the 110-series platform has no provision for an internal heater. Raise your water heater temperature to 120°F, and run the hot water at the laundry sink for 30 seconds before starting the washer to purge cold water from the pipe.

My washer uses cold water no matter the setting — is the control board bad?#

Unlikely. Check the hot-side inlet-valve solenoid first: if its winding is open, only cold water enters regardless of what the board commands. That is a valve replacement rather than a board replacement.

Why is my water lukewarm on every cycle?#

Usually a partly blocked inlet screen restricting flow on one temperature, or a household water heater set too low. Clean the screens and raise the heater above 120°F before suspecting the machine.

Why won't the Sanitize cycle get hot enough?#

On the 796 and 417 models that heat, a burned-out heater element or a failed thermistor is to blame. Test the NTC thermistor for about 50,000 ohms cold and check the element for continuity.## What 'no internal heater' means for what you can expect

The single fact that reframes this complaint is that most of these machines never heat water at all. They open a hot valve and a cold valve in some proportion and wash with whatever arrives, which has three practical consequences worth spelling out.

A long run to the laundry room caps your hot wash. Every metre of pipe between the water heater and the machine holds cold water that has to be pushed through before hot arrives, and on a short fill the machine may finish filling before that happens. The wash is then cooler than the setting regardless of the setting.

Your water heater's thermostat is the real temperature control. A tank set conservatively gives a washer no way to reach a hot wash, and no part inside the machine can compensate.

Winter changes the answer. Incoming cold water is genuinely colder in winter, so a warm setting that blends hot and cold arrives cooler in January than in July with nothing having changed in the appliance.

Only the series that do carry a heater escape this, and even those heat only on the specific cycles that call for it.
