Maytag MDBH970AWB dishwasher Parts

On a Maytag MDBH970AWB dishwasher, the E1 F9 (often shown as F9E1) code points to a drain problem. We fix it by clearing the drain path (disposer, air gap, hose, filters) and then running a cancel-drain to force the unit to pump water out; see the MDBH970AWB owner's manual for the exact cancel/drain steps.

What to check first (fastest fixes)

• Turn off power at the breaker before reaching into the sump or wiring.
• If you have a garbage disposer, make sure it is empty and run it to clear food buildup.
• Check the sink drain connection for a clog and confirm the dishwasher drain hose is not kinked.
• If an air gap is installed, remove the cap and clear debris.
• Make sure the door fully latches; some models will not complete drain if the cycle is interrupted.

Force a drain (cancel-drain)

The manual describes using the START/Cancel pad to stop a cycle and activate draining. In many cases, pressing START/Cancel once starts the cancel function, and pressing it again triggers the drain pump to run.

What you see	What it usually means	What to do
Water sitting in tub bottom	Drain path restricted	Clear hose/air gap/disposer, then cancel-drain
Humming but little or no draining	Pump is running but flow is blocked	Check filters/sump area for debris
No drain sound at all	Drain not being commanded or latch/power issue	Verify door latch and power, then retry

When a part is likely needed

If the drain path is clear but the dishwasher still will not drain, a failed drain component is common.

• Drain hose split, soft, or internally blocked: replace the dishwasher drain hose WP99002652
• Latch not holding the door closed: inspect/replace the latch WPW10275768
• Poor wash and recurring debris in the sump can contribute to drain issues: inspect the dishwasher chopper WP99002658

Why it matters

A drain fault leaves dirty water in the tub, can stop the cycle mid-program, and often causes repeat error codes. Clearing the drain path first prevents unnecessary part replacement and restores normal cycle operation.

On the Maytag MDBH970AWB dishwasher, you reset (turn off) Control Lock by pressing and holding the Heated Dry pad for 3 seconds until the lock indicator light turns off. This unlocks the touchpads so you can select a cycle and press START/Cancel normally. See the MDBH970AWB owner's manual.

How to unlock Control Lock (step-by-step)

• Make sure the dishwasher door is closed.
• Press and hold Heated Dry for 3 seconds.
• Watch for the lock indicator to turn off.
• Try pressing a cycle pad; it should respond normally.
• Start the cycle by pressing START/Cancel.

What you will see when Control Lock is on

When Control Lock is active, the dishwasher controls are disabled (the door is not locked). If you press pads while locked, the lock indicator typically flashes.

What you notice	What it usually means	What to do
Lock indicator light is on	Controls are locked	Hold Heated Dry 3 seconds
Pads do not respond	Control Lock is active	Unlock, then reselect cycle
Lock indicator flashes when you press a pad	You are trying to change settings while locked	Unlock first

If the dishwasher still will not start after unlocking

Control Lock is only one “no-start” cause. These checks solve most start issues on MDBH970AWB:

• Press START/Cancel within about 30 seconds of choosing a cycle (otherwise the dishwasher can turn off).
• Confirm the door is fully latched; a loose latch can prevent starting.
• Cancel and restart the cycle: press START/Cancel once to drain and shut off, then select a cycle and press START/Cancel again.
• If the door will not latch securely, inspect the latch WPW10275768 and the door strike WP99002644 for wear or misalignment.

Why it matters

Control Lock prevents accidental cycle changes, but it can look like the dishwasher has “dead” controls. Unlocking it restores normal keypad operation so you can run a wash cycle and avoid unnecessary part replacement.

A Maytag dishwasher typically lasts 10 to 12 years with normal household use. For your Maytag MDBH970AWB, consistent cleaning, correct loading, and fixing small issues early can push real-world life closer to the high end of that range.

Typical lifespan (what to expect)

Most residential dishwashers fall into a predictable lifespan range based on use and maintenance.

Usage pattern	Typical lifespan	What usually ends a dishwasher’s life
Light use (few loads/week)	12 to 15 years	Leaks, rack rust, door seal wear
Average use (1 load/day)	10 to 12 years	Pump wear, heater issues, control problems
Heavy use (2+ loads/day)	7 to 10 years	Motor/pump wear, repeated clogs, corrosion

What extends the life of a Maytag dishwasher

These habits reduce strain on the pump, heater, and wash system.

• Scrape food off dishes instead of heavy pre-rinsing (helps the wash system work as designed).
• Keep the filter area and sump clean so water flow stays strong.
• Make sure spray arms spin freely and holes are not blocked.
• Use the right detergent amount for your water hardness.
• Run hot water at the sink before starting a cycle so the dishwasher fills with hotter water.
• Fix small leaks and draining issues quickly to prevent damage to wiring and components.

Parts that commonly affect longevity

When performance drops, these are common wear items that can restore normal operation.

• Heating and drying problems: Heater element W10283681
• Not filling or filling slowly: Dishwasher water inlet valve W11082871
• Poor wash pressure or noise: Dishwasher pump impeller WP99002659
• Door not closing or starting issues: Latch WPW10275768

Why it matters

A dishwasher that is not heating, not filling correctly, or not circulating water well often runs longer, cleans worse, and puts extra load on the motor and pump. Keeping MDBH970AWB operating “normally” is the simplest way to hit the full expected lifespan.

For model-specific care, cleaning intervals, and operating tips, follow the MDBH970AWB owner’s manual.
