Check where the hose connects to the washer sometimes their is a screen filter in their. If not the valve that controls the water input could be bad. Most of those valves are where the hoses hook to the washer.
Remove the front panel and open the control panel.
Remove the platic hose from the water level switch and the air dome on the side of the tub.
Clean the soap out of the air dome hole witha toothpick Blow through the plastic hose. Re-connect everything. Set the washer to spin and turn it on for 1 minute.
Then run a regualar wash cycle.
You can ususally take your Hotpoint washing machine out of DEMO MODE by holding down both the ON/OFF button and the START/RESET button at the same time for about 3 seconds.The display should then indicate D OFF.If this procedure does not work for your particular machine, then please just comment back and be sure to include the exact model number of your washer next time so we can provide the appropriate procedure for your appliance. Good luck.
The first thing to always try is disconnecting it from the mains plug overnight. Then in the morning press and hold the power button for 60 seconds. Then plug it back in. The is a Power Reset on a machine that has an electronic mainboard.
Does water enter the machine? My guess is that the water inlet valve may have failed. It waits, no water comes, so it times out. There are a few things to check there, make sure there is water in the pipe, make sure the strainer screens are clear in the hose connecter on the back of the machine.
No model details given but there is help in the link.
