Whirlpool Dishwasher: not filling
What is this symptom?
Experiencing issues with your Whirlpool Dishwasher not filling with water? This common problem may occur when the appliance starts its cycle but either no water or only a small amount enters the tub. Understanding the potential causes can help you troubleshoot effectively.
Important Tips for Whirlpool Models
- Whirlpool official support emphasizes checking the water supply valve, door latching, and drain hose loop height to prevent siphoning before deeper component troubleshooting.
Possible Causes
Water inlet valve failure or blockage
How to Identify: Dishwasher powers on and sounds normal but no water enters; inlet screen may be visibly clogged with mineral debris; water pressure to valve is adequate.
Part: Water inlet valve
Float or float switch malfunction
How to Identify: Float in bottom of dishwasher does not move freely or float switch doesn’t signal, preventing inlet valve activation; dishwasher makes noise but remains dry.
Part: Float assembly / float switch
Water supply issues (valve off, kinked line, low pressure)
How to Identify: Dishwasher receives no water from house plumbing; supply valve not fully open or supply line kink/blockage present.
Part: Water supply valve/line
Control board or electronic control failure
How to Identify: Other components test OK but inlet valve never receives signal to open; dishwasher runs cycles without filling.
Part: Control board / electronic timer
