Common Causes for Standing Water in Dishwashers
If the quick checks do not solve the problem the issue likely lies deeper in the appliance. Here are the most frequent mechanical failures.
Drain Pump Failure
The drain pump uses an impeller to push water out. Over time the impeller can jam on debris or the motor bearings wear out. A failing pump often hums or clicks but moves no water. Testing requires a multimeter to check for 120 volts at the pump terminals during the drain cycle.
Check Valve Stuck Closed
Many dishwashers have a one-way check valve to prevent backflow. If debris lodges in the valve it stays shut and water cannot exit. This is common in homes with older galvanized pipes where rust flakes can travel into the valve.
Float Switch Malfunction
The float switch monitors water level and stops the fill cycle if it detects too much water. If the float sticks in the up position the control board may think the tub is already full and skip the drain step entirely. Gently lift and lower the float to see if it moves freely.
Solenoid Valve Issues
Some models use a solenoid to open the drain line. A faulty solenoid coil will not energize even when the control board sends the signal. Testing involves checking resistance across the coil with a multimeter; a reading of zero or infinite ohms means replacement is needed.
Baltimore Hard Water and Your Appliances
Baltimore draws from surface water sources with moderate to high hardness around 7 to 10 grains per gallon. Over time dissolved calcium and magnesium form scale inside drain lines and on pump components. This buildup narrows passages and forces the pump to work harder until it fails. Homeowners in Morrell Park often notice white residue on dishes and cloudy glassware long before a complete breakdown. Installing a phosphate filter on the dishwasher supply line can slow mineral accumulation and extend component life.
