How to Fix a Dishwasher That Won’t Start

A dishwasher that refuses to start can be caused by something as simple as a loose door latch or as complex as a failed control board. Before spending money on a service call, work through these common causes in order. Many no-start issues are fixable in minutes without any tools.

Check 1: Is It Getting Power?

Start with the basics:

• Is the power switch on at the wall? Dishwashers are often switched off at the wall and forgotten.
• Has the circuit breaker tripped? Check your switchboard and reset if needed.
• Is the power cord fully seated in the outlet? Give it a firm press.

Check 2: Is the Door Latched?

Dishwashers have a safety switch that prevents operation if the door isn’t fully closed and latched. Push the door firmly closed until you hear or feel the latch click. Try starting again. A worn or broken door latch that no longer engages the switch is a common fault — inexpensive to replace.

Check 3: Is the Child Lock On?

Many dishwashers have a child lock or control lock that disables all buttons. Check your manual for how to deactivate it — typically by holding one or two buttons for 3–5 seconds until an indicator light changes.

Check 4: Is the Water Supply Connected?

Dishwashers won’t start a cycle if they cannot fill with water. Check:

• Is the water supply tap (usually under the sink) fully open?
• Is the fill hose kinked?
• Is there a water pressure issue in the house?

Check 5: Is There a Delay Start Set?

Many dishwashers have a delay start function that queues a wash for 1, 2, 4 or more hours later. If you accidentally activated delay start, the machine won’t begin immediately. Check the display for a timer counting down and cancel if needed.

Check 6: Check the Error Code Display

If your dishwasher is showing a fault code on the display, look it up in the manual. Common fault codes include:

• E1 / Water fill error: No water entering. Check supply tap and hose.
• E2 / Heating fault: Heating element or thermostat fault.
• E4 / Overflow: Water level sensor triggered. Turn off and check for leaks.
• E9 / Door fault: Door latch sensor not reading correctly.

Check 7: Perform a Reset

Switch the dishwasher off at the wall, wait 5 minutes, then switch back on. Some electronic faults clear completely with a full power cycle. Run a short program after resetting.

When to Call a Technician

Call a technician if:

• None of the above steps resolved the issue
• The machine shows error codes that don’t clear
• You can hear the machine trying to start but nothing happens
• The control panel is unresponsive even after a power cycle
