This is a tricky one and can bite you in the rumpus if you don't know about this quiet little Whirlpool Service Pointer on this problem that Brother Chat_in_FL snagged and posted for us:

Service Pointer
W10398386

Serial Numbers: F032 to F105

Customer Concern:
Dishwasher stops approximately 10 minutes into the cycle, “cancel drains” and goes directly to standby mode (off).

Cause:
Testing has determined that cycle stopping may result from a software error that can cause a false error code that cancels the cycle. Techs will see a 6-1 error code recorded in service diagnostics. This issue is very sporadic, and is affected by the location of the household and region of the country. Other conditions that may also cause this “cancel drain” cycle are: siphoning through the drain hose, severe sudsing, and debris in the sump.

Correction:
If the customer experiences a “cancel drain” issue, first check the following:
1. Make sure the dishwasher is installed according to installation instructions provided with the unit.
2. Check for water siphoning out through the drain hose. Ensure that the drain hose end termination point is above the water level in the tub. The drain loop attached to the side of the tub is not sufficient to prevent siphoning.
3. Check for severe sudsing or a malfunctioning Rinse Aid dispenser.
4. Check for locked rotor in wash pump.
5. Check for and remove debris in the bottom of the sump/chopper area.
6. Check for water supply and proper water level in the dishwasher.
7. If all the above checks are OK, then the control will need to be replaced with one that has the upgraded software designed to handle any additional power variation. See chart below for part numbers. Testing has determined that cycle stopping may result from a software error that can cause a false error code that cancels the cycle.

Brother PDuff calls the dance steps on this little ditty:

Remove bottom access panel and check main control for any lit leds. Lit led is specific to affected component. Access Component/Relay/Triac test as follows:

From power up press Sanitize and Delay Start
"Et" should be displayed (engineering test)
Press Rinse Only
"rt" should be displayed indicating component test mode. Press the following buttons to toggle on/off each component:

Auto Sense-washer motor
Heavy-water valve
Normal-drain motor
Quick-drain valve
Rinse Only-Clean light led
Hi Temp-all leds on control housing
Sanitize-fan state
Air Dry-dispenser

When checking heater, always fill tub with water.

Brother PDuff explains the esoteric and mystical art of programming the control codes in Bosh dishwasher control boards using model SHE44C06UC/22 as an example:

Control codes are particular to model. C0-C4. Your model is a C1 control. With unit turned off and fascia removed and module exposed, there are six buttons. Ignore the first button under display and label remaining buttons from left to right S1 S2 S3 S4 and S5. The leds above each button label L1 L2 L3 L4 and L5. Enter coding mode as follows:

Press and hold buttons S2 S3 S4 and S5 simultaneously, then turn dishwasher on using on/off switch. When in coding mode leds L2 L3 L4 and L5 will be blinking.

Release buttons S2 S3 S4 and S5 to view control coding in display. To change control coding, press button S2 as needed to scroll through codes. Your model is C1 or 21.

Turn dishwasher off to save control coding and exit mode. Reinstall control to console. Reinstall fascia. Check operation.

When the electromagnet pulls the plunger down, it doesn't close the drain flapper all the way, (only about 3/4 of the way closed), then the water pressure hits the flapper and holds it sealed against the spray arm outlet so the water goes out the drain.

When the water pressure hits the drain flapper and opens it the rest of the way it takes the load off the solenoid. The solenoid is only energized for about 30 seconds and if it finishes draining before the the timer turns off power to the drain solenoid then the return springs will pull pressure against the magnetic force of the solenoid and can cause the buzzing noise.
