Hotpoint Dishwasher C3 Error Code: Causes & Fix

What is the Hotpoint Dishwasher C3 error?#

C3 on a Hotpoint dishwasher means the drain pump is not clearing the tub: water is left standing at the end of the cycle. It is low-risk and often owner-fixable, and the first thing to do is clean the filter — twist out the filter cup in the sump well and rinse the packed food film off its mesh.

C3 on a Hotpoint Dishwasher: likely causes and repair cost#

On a Hotpoint Dishwasher, the C3 code signals: drain pump not clearing the tub.

Typical professional repair: $100–$225 · Difficulty: moderate · often owner-fixable

Fastest thing to try first: Clean filter and check for blockage.

Symptoms that often accompany C3: Water left standing in the tub at the end; A gurgle from the drain as it tries to pump; Dishes rinsed dirty by the backed-up water

Technician diagnostic sequence for C3:

1. Twist out the filter cup in the sump well and rinse the packed food film off its mesh
2. Probe the sump beneath for a glass sliver or a soaked-off can label snagging the vanes
3. Cue a drain and listen — a hum with no outflow is a jammed impeller, dead silence is a spent motor
4. On a disposer hookup, make sure the knockout slug was punched out or the pump has nowhere to send water

Parts a technician may check or replace: drain pump assembly; filter assembly

Field note: Valley hard water crusts scale inside the pump volute over time and drags the impeller. Run a citric-acid descale cycle and re-test the drain before you commit to a new pump, since a scaled but sound pump often frees right up.

How to troubleshoot the C3 error yourself#

C3 is frequently a job you can finish yourself, starting at the sump. Twist out the filter cup in the sump well and rinse the packed food film off its mesh — a filter matted with soil is the most common cause. Then probe the sump beneath the filter for a glass sliver or a soaked-off can label snagging the impeller vanes, which will foul the pump without fully stopping it. Cue a drain and listen: a hum with no outflow means the impeller is jammed, while dead silence means the drain motor is spent. If your dishwasher connects to a garbage disposal, make sure the disposal knockout slug was punched out, or the pump has nowhere to send the water — a classic overlooked cause on new installs. One more thing worth trying before spending on a pump: in hard-water areas, scale crusts inside the pump volute over time and drags the impeller, so running a citric-acid descale cycle and re-testing the drain often frees a scaled but otherwise sound pump. If the filter is clean, the sump is clear, the disposal is open, and C3 still shows with a dead-silent drain, replacing the drain pump is a technician job.

Is the Hotpoint Dishwasher C3 error worth fixing?#

C3 is usually worth fixing and often costs nothing, since a cleaned filter or a cleared sump resolves most cases for free. When a part is needed — a drain pump or filter assembly — the professional range is $100 to $225, minor against a comparable new dishwasher. Because a scaled but sound pump frequently frees up with a descale cycle, it pays to try that before committing to a new pump. On any reasonably aged machine, restoring proper drainage for that price clearly beats replacement, and a drain fault says nothing about the wash system or heating.

Hotpoint Dishwasher C3: frequently asked questions#

What does C3 mean on a Hotpoint dishwasher?#

It means the drain pump is not clearing the tub, so water stands at the end of the cycle. The usual cause is a soil-matted filter or an impeller fouled by a shard or label.

Is it safe to keep using a dishwasher showing C3?#

There is no safety risk, but water sits in the tub and dishes rinse dirty. Clean the filter and clear the sump before running it again.

Can I clear C3 myself?#

Often, yes. Cleaning the sump filter, clearing any shard from the impeller, and confirming the disposal knockout was removed fixes most C3 cases. A dead pump needs a technician.

How much does it cost to repair C3?#

Frequently nothing when the fix is the filter or a cleared blockage. When a drain pump or filter assembly is needed, a professional repair runs $100 to $225.

Can hard water cause C3?#

Yes — scale crusts inside the pump volute and drags the impeller. Running a citric-acid descale cycle and re-testing the drain often frees a scaled pump before you replace it.

Is a Hotpoint dishwasher with C3 worth repairing?#

Yes — it is a low-cost, often-free drain fault, so on any reasonably aged machine repair is clearly better than replacement.
