All the lights are flashing

Dishwasher lights flashing or blinking. The heating element heats up the water to operating temperature. If the water doesn't reach the proper temperature after a set amount of time, a light on the control panel might start flashing. ... If the drain pump is not working, a light on the control panel might start flashing. https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Dishwasher/28---/Dishwasher-Lights-Flashing-Or-Blinking
Flashing lights and or beep sounds can mean the dishwasher problem was from a power surge or power outage. You can unplug the dishwasher from power or shut off the breaker to the dishwasher for 1 minute. This may reset the dishwasher and get it back to working order.

You have inlet hose and drain hose so it is possible to water leakage on both. The easiest access to both hose is from bottom of dishwasher.

• Remove the bottom panel
• Remove the inner filters
• Remove any residual water from the sump by
  suction, so that it does not flow into the tub and the
  pressure switch tubes, then lay the appliance on its
• Unscrew and remove the regulation screw from the
  rear foot (built-in versions only).
• Remove the screws which secure the bottom panel
  to the base (three screws)
• Release the built-in retaining elements placed on
  the right and rear side: and remove the bottom
  panel by sliding to the right.
• You are able now to access any bottom parts

Like most electrical appliances what worked for me was turn it off at the wall for 10 mins, then turn it back on. Did you get an error code? Check the pipes are not twisted and that the water supply is turned on full. Let me know how you get on

check the hose of water intake

is it a whirlpool washer an f7 is the reg dosage card. This is placed on the right hand side behind the side panel. The card works by counting the revolutions of a water wheel when a certain amount of water has entered the appliance then it will begin washing.

Hope this helps

6 flashes indicates water intake fault ie machine is saying it has not filled with water within the required time.
-Check inlet hose not kinked or blocked.
-Next, check inlet valve is OK (check with ohm meter-should read approx 4k ohms). If no circuit thru valve, replace.
-Could also be fault with water indicator switch (much harder to access and diagnose- located underneath sump on right hand side).
-I have also had this occur because of a faulty flow meter. Flow meter measures the volume of water as machine fills. Flow meter is large plastic chamber located on left hand side of machine (accessed by removing left hand side panel). It has a sensor on the bottom with 2 blue wires. Unfortunately again, very hard to test this component without specialist equipment.
Hope this is some help- not sure how technically minded you are, but checking inlet hose for kink/obstruction is a good place to start, then advise calling service technician unless you are a confident DIYer

An Idea: the Overflow sensor or float is bad, stuck, disconnected and its messages to STOP filling aren't getting thru to the CPU

This is usually located in the right frony of the machine or in the side wall. Float types get gummed up with 1/2 dissolved soap powder (god what we do tho the water systems) see if it moves. Sensor types have a hole that feels or senses water. If clogged, they lie. Clean out with toothpick and blast with a bit of hot water and air. Retry

If fixed, let me know... if not, see the yellow pages for parts dealers ;-)

Switch off and unplug before doing anything. .

First three lights are flashing on top and it will not stop making stupid noises.

Remove plastic panels at front of machine under door, see if there is water inside.

If there is ... something is leaking. If it is a slow leak - solution is to dry up excess water in tray with paper towels or whatever comes to hand. You will need to find the leak somehow - salt container is usual suspect.

There is a microswitch attached to a float on the left hand side inside a white plastic cover. Water at the base of this activates the switch and disables machine. Mine has not leaked since trying this fix and machine is running well 2 months down the line. Better 10 minutes with paper towels than 2 hours of expensive plumbers.

check your overflow level switch wich is located behind front kickplate on right hand side
