KitchenAid KUDP02CRBS1 dishwasher Parts

The F9 E1 error on your KitchenAid KUDP02CRBS1 dishwasher points to a draining problem (water is not leaving the tub fast enough). We fix it by clearing the drain path first, then checking the drain hose and drain pump, and finally testing the electrical safety fuse if the unit stops mid-cycle. See the troubleshooting and cycle steps in the KUDP02CRBS1 owner's manual.

Step-by-step checks (start with the easiest)

• Turn off power at the breaker before servicing.
• Cancel the cycle and let the dishwasher attempt to drain.
• Remove standing water (if needed) so you can inspect the sump area.
• Check the drain hose routing for kinks, crushing, or a clogged high loop/air gap.
• Inspect the sink/disposer inlet where the dishwasher drain connects (common clog point).
• If the drain path is clear but it still will not drain, suspect the drain pump.

Parts that commonly solve F9 E1 on this model

If the drain path is clear and the dishwasher still will not pump water out, these parts are the most common fixes:

Symptom you see	Most likely area	Part to consider
Hums but does not move water	Drain pump jammed or failed	Dishwasher drain pump WPW10348269
Drains slowly or backs up	Restricted or leaking drain line	Dishwasher drain hose 8269144A
Dead/no response after a drain issue	Control protection opened	Fuse W10258275

Quick functional test after a repair

Our installation guide recommends verifying operation by running the shortest wash cycle and checking for water in the tub after the first couple of minutes. After you restore power:

• Start the shortest cycle.
• After about 2 minutes, unlatch the door, wait 5 seconds, then open.
• Confirm there is water in the bottom of the tub (proves filling).
• Let it continue and confirm it drains at the end.

Why it matters

A true F9 E1 drain fault can leave dirty water in the tub, cause odors, and stop the cycle early. Clearing restrictions first prevents unnecessary part replacement and helps protect the pump motor and electronic control.

On the KitchenAid KUDP02CRBS1 dishwasher, the Clean light typically turns off after a full cycle completes normally. If the Clean light is flashing, it indicates a malfunction (commonly in the heater circuit) and a simple reset usually will not clear it until the underlying issue is corrected; use the troubleshooting steps in the KUDP02CRBS1 owner's manual.

What the Clean light means on this model

From the troubleshooting guidance for this dishwasher:

• Clean light flashing: the dishwasher has malfunctioned and the heater circuit needs to be checked.
• Clean light on steady: the cycle finished normally.
• Clean light does not come on: the cycle may have been canceled, interrupted, or power was lost.

Reset steps we recommend first (safe, no tools)

Try these in order to clear a stuck control state and confirm the dishwasher can complete a cycle:

• Press Cancel/Drain (or the model’s cancel function) and let it finish draining.
• Turn power off at the breaker for 1 minute, then restore power.
• Start the shortest wash cycle and let it run.
• After about 2 minutes, unlatch the door, wait 5 seconds, then open and confirm there is water in the bottom of the tub.
• Let the cycle finish; the Clean light should come on steady at the end.

If the Clean light is flashing (most common cause)

A flashing Clean light on KUDP02CRBS1 points to a heater circuit problem. These checks help narrow it down:

What to check	What you’re looking for	Related part (if needed)
Water temperature	About 120°F (49°C) entering the dishwasher	None
Heating function	Cycle pauses while heating; no heat can trigger faults	Heater element WPW10082892
Overheat protection	Open safety device can stop heating	Dishwasher thermostat WP661566
Control protection	Blown protection device can cause no-heat/no-run symptoms	Fuse W10258275

Why it matters

The Clean light is more than a “status” indicator on this KitchenAid dishwasher. When it flashes, the dishwasher is telling you it detected a condition that can prevent proper heating, cleaning, and drying, and it may stop mid-cycle to protect components.

On the KitchenAid KUDP02CRBS1 dishwasher, a blue light is typically a cycle status indicator (the dishwasher is running, in a delay, or has completed a cycle). If the light is blinking or the dishwasher will not run, check for a control lock, a paused cycle, or a fault indicated by other lights in the console; confirm the exact light behavior in the KUDP02CRBS1 owner's manual.

What to check first (quick, safe steps)

• Press Cancel/Drain once, then press Start/Resume to restart the cycle.
• Make sure the door is fully latched; many models will flash a status light if the door is not latched.
• If the dishwasher seems “stuck,” wait a few minutes; some cycles pause briefly during the main wash.
• Check your home power: a tripped breaker or blown household fuse can leave the control acting odd.
• If the unit has power but will not run, look for a control lock or a delayed start setting.

If the blue light is blinking or you see other warning lights

Some KitchenAid dishwashers use a flashing status light along with other indicators to point to a problem.

What you see	What it usually means	What to do next
Blue light solid	Cycle is running or in progress	Let the cycle finish; avoid opening the door often
Blue light blinking	Paused cycle, door not latched, or a fault	Re-latch door; press Start/Resume; then check for error indicators
Clean light flashing	Heater circuit fault is suspected	Stop the cycle and troubleshoot heating components

If you get a heater-related symptom (for example, Clean flashing), common repair paths include checking the heating circuit and related parts such as the heater element WPW10082892 and the dishwasher thermostat WP661566.

Why it matters

The status light helps you tell the difference between a normal pause (sensor checks, water heating, or programmed delays) and a true problem like a heating fault or a door-latch interruption. That saves time and prevents unnecessary part replacement.
