Hotpoint Dishwasher Flashing/Blinking Problems

When you’ve popped a load of washing into your Hotpoint dishwasher and tried to turn it on, the last thing you want to see is a flashing or blinking light.

Here are a few reasons why your dishwasher’s lights might be flashing.

If your Hotpoint dishwasher control panel lights are flashing you could have a problem with the water inlet, drain pump, heating element, or heating element assembly. Touchpads can also wear out, causing flashing lights and errors. Consult the user manual to help to isolate the problem.

If your water inlet is blocked or the tap switched off, the on/off light will flash. Check that the tap or stopcock is turned fully open.

If water is still not flowing into the dishwasher, then check for a blockage in the inlet pipe.

A quick visual check will let you know if the display panel is operating correctly.  Push the buttons on the control panel to see if they are working. The control panel may be faulty if it does not respond when you press some of the buttons.

When the lights flash, an error code should appear on the screen. Your Hotpoint dishwasher manual has a list of the more common error codes.

If the drain pump has a problem, it is most usually the impeller. Unfortunately, a faulty drain pump must be replaced as they are not items that you can repair.

Heating elements and the heating element assembly are also prone to failure in older dishwashers. A flashing light indicates that the water has not reached the required temperature. Performing a continuity check will confirm whether the element is faulty and needs replacement.

Hotpoint Dishwasher Green Light Flashing

You may find that the green light flashes on your dishwasher shortly after you close the door.

If a green light flashes on a Hotpoint dishwasher, it may be due to a cycle interruption. The door may not be closed properly or the power has been interrupted. This stops the cycle and the light flashes. To fix this, switch the machine off, switch the machine off and on again, then close the door.

It is important that you close the door within 3 seconds of resetting the dishwasher so that the wash cycle continues from where it stopped.

A flashing green light may also indicate that the water inlet is blocked or off. Check that your dishwasher is receiving water and that nothing is blocking the pipe.

If the filters are blocked, you may need to hold the on/off button down for 3 seconds, which will reset the dishwasher.

Hotpoint Dishwasher Start Light Flashing

It can be very frustrating if the start light flashes green for no apparent reason.

To fix a Hotpoint dishwasher start light flashing, hold the on/off power button down for 3 seconds to reset the dishwasher. Alternatively, hold the power button for 10 seconds so that the dishwasher can go through a self-cleaning cycle. Also, check that the drains and filters are not clogged.

Water inlet problems may be indicated via a “6” or “H” showing on the control panel display.

A flashing green light is sometimes caused by a leak. If water collects in the bottom of the dishwasher, it may trigger a cut-off switch and initiate the flashing green light.

To fix this, inspect the pump and water hoses to trace the leak.

Hotpoint Dishwasher Power Light Flashing

As dishwashers age, parts such as the heating element are prone to failure.

This requires the replacement of the element.

A timer checks if the dishwasher water reaches the correct temperature within a set time. If it does not, then a light on the control panel will flash, indicating that there is a problem. The element may have burned out. To check, perform a continuity check on the element to see if it’s the culprit.

The heating element is built into many pump units. So, rather than checking continuity at the plug, check it on the contact points of the element.

To access the pump, you may have an access hatch on the side of the dishwasher or underneath.

Unplug the dishwasher from the electricity supply and close the water intake tap or stopcock. Take it out of its cabinet so you have room to work.

You may have to tip the dishwasher onto its back so that you can access the hatch underneath. Unclip or unscrew the hatch and locate the pump. The heater element is located close to or is part of the pump assembly.

Once you have performed a continuity check on the element, replace it if it is faulty.

Hotpoint Dishwasher Pause Light Flashing

A flashing pause light can be an indication of serious problems with your Hotpoint dishwasher.

The flashing light may be accompanied or preceded by abnormal noises during the wash cycle. You may also find that the dishwater does not start properly.

A Hotpoint dishwasher pause light flashing can mean that the recirculating pump is burnt out. To check the pump, remove the dishwasher from the cabinet. Switch off the water and power and open the access hatch. Tip the dishwasher on its side and remove the pump. Replace it if it’s faulty.

To access the pump, remove the baseplate and disconnect the anti-flood switch connectors. Remove the hose attached to the pump and then disconnect the ground wire and connectors.

Unscrew the pump’s retaining screw and remove the pump. You’ll have to remove the last of the hose fittings before lifting the pump out of its recess.

Select the ohm setting on your multimeter and test the resistance across the terminals. If you have a reading of fewer than 100 ohms, the pump is faulty and needs replacement.

If the resistance is fine, check to see if the motor is seized. Use a screwdriver to turn the motor in the spindle slot. Make sure that it rotates freely. If not, the motor is seized and must be replaced.

Hotpoint Dishwasher Wash Light Flashing

If you have a problem with the amount of water or type of dishwasher cubes you’re using, you will have flashing lights on the control panel.

A flashing wash light on a Hotpoint dishwasher is normally a sign that the water temperature is not optimal. There may also be too little or too much water in the dishwasher, or there could be an excess of foam inside. You must reset the dishwasher by holding the power button down for 3 seconds.  

Once you hear a beep from your dishwasher, you know that it has reset itself.

Often you will press several buttons before trying to reset the dishwasher. This can cause the dishwasher to malfunction. If that happens, and the lights don’t stop flashing, disconnect the power cord or switch the dishwasher off at the main electrical panel.

Wait for a minute or two and then reconnect the power.

Switch the dishwasher on and wait to see if the lights continue to flash.

If they do, then you may have inadvertently engaged the child lock function. To stop the lights flashing, you’ll have to disengage the child lock by holding the power button down for a few seconds. Your particular dishwasher may have a different method to cancel the child lock, so check the manual.

Check that the door is closed securely and cancel sleep mode if it has been engaged.

A “delay start” function is also a possible reason for the dishwasher failing to start after restoring power and resetting the machine. Open and close the door, then press the “delay start” button to disengage the function and initiate the washing cycle.

Common problems with Hotpoint dishwashers will cause the lights to flash or blink. You may have a faulty circulation pump or burnt-out motor. Heating elements and the heating element assemblies also cause problems that result in the lights flashing, as does a faulty door latch.
