The W11087226 is a genuine OEM dishwasher electronic control board for Whirlpool and affiliated brand dishwashers. This control board is the "brain" of the dishwasher, managing all electronic functions and operations including wash cycle timing, water temperature control, motor speed control, drain pump operation, detergent dispenser activation, rinse aid dispenser control, heating element control, drying cycle control, cycle selection, and diagnostic functions. The control board is a printed circuit board assembly (PCBA) constructed from high-quality fiberglass substrate with surface-mounted electronic components including microprocessors, relays, capacitors, resistors, diodes, triacs, and integrated circuits, mounted on a durable plastic support bracket. The assembly measures approximately 10-11 inches in width and 7-8 inches in height, weighing approximately 1-2 pounds. The control board has multiple electrical connectors (typically 8-12 wire harnesses) for connecting to various dishwasher components including the motor, water inlet valve, drain pump, heating element, detergent dispenser, user interface, door latch, temperature sensors, and power supply. The W11087226 replaces older part numbers including W10919360, W10906426, W10906427, W10906428, and others with improved reliability, functionality, and diagnostic capabilities. The control board operates on 120 volts AC, 60 Hz and draws approximately 1-3 amperes during normal operation. The board contains a microprocessor that monitors sensors throughout the dishwasher and controls all cycle operations based on the selected wash program. The board manages water filling by activating the water inlet valve, controls water temperature by activating the heating element, controls motor speed and direction for wash and drain cycles, activates the drain pump to remove water, dispenses detergent and rinse aid at appropriate times, and manages the drying cycle by controlling the heating element and fan. Over time, dishwasher control boards can fail due to capacitor failure (electrolytic capacitors dry out over time), relay failure preventing proper component activation, triac failure preventing motor or heating element operation, microprocessor failure from electrical surges or overheating, solder joint failure from thermal cycling and vibration, component corrosion from moisture exposure, power surge damage from electrical faults, or manufacturing defects. When the control board fails, symptoms include the dishwasher not starting at all (no power), the dishwasher not filling with water (inlet valve not activating), the dishwasher filling but not washing (motor not running), the dishwasher not draining (drain pump not activating), the dishwasher not heating water (heating element not activating), the control panel display not working or showing error codes, control panel buttons not responding, the detergent dispenser not opening, the dishwasher stopping mid-cycle, unusual clicking or buzzing sounds from the control board area, or the dishwasher cycling through functions erratically. The W11087226 is a complete replacement electronic control board that restores full dishwasher operation and all electronic functions. Replacing a faulty control board eliminates all control board-related problems and restores reliable, precise dishwasher operation. Important: Always turn off power at the circuit breaker before working on the dishwasher. This is an advanced repair requiring careful handling of electronic components and precise reconnection of multiple electrical connectors (typically 8-12 wire harnesses). Verify your dishwasher model number before ordering. Test the control board with a multimeter before replacement to confirm control board failure. This repair may require professional installation if you are not comfortable working with electronic components and multiple wire harness connections.
