When I attempt to select the wash cycle (heavy light etc) all the lights come on and does not allow me to make any selection. I have tried turning off at mains but still same result.

It appears that the control board and the dials are broken on your washing machine.

2.13.1 Scrud
If fabric softener is used regularly it will eventually cause a build up within the outer bowl. This can
result in black flakes present in the wash load that can stain garments. To remove scrud follow the
procedure below.
Step1: Add a full cup of a good quality dishwashing powder such as Active or a similar product
into the machine.
Step 2: Set the machine to a Heavy Duty cycle, select a Hot Wash temperature, High Water level
and allow the machine to agitate for 10 minutes.
Step 3: Leaving the lid closed, turn the machine off and allow to soak overnight.
Step 4: The following day, turn the machine on and advance to the spin cycle to drain the water
from the machine. After the water has drained, turn the machine off then back on again, and select
a Heavy Duty cycle, Hot wash, High Water level, and allow the machine to complete a full cycle to
ensure that all of the loose scrud and residual detergent has been flushed away.
Note: If there is an extremely heavy build up the bowl will have to be removed for pressure washing

unplug it for about 5 minutes,, that is the door lock code,, it should reset itself in that time,, just close the door and try it again

you dont need to reset the times, all that has changed is the soil type. in example, light, regular or heavy. that is what causes the times to change.
you just need to push the options button until it shows the type of cycle you want.
also make sure you have the proper cycle selected and then look to see what other options are selected. you just have too many options turned on, so look at the controls to see what is different then you remember.

Pressing the options and select buttons simultaneously for 5-10 seconds worked. For me it happened this way: on the first attempt, with the indicator lights already "timed-out" and off, pressing and holding the options and select buttons simultaneously for 5-10 seconds caused the lights to come back on and flash the "LOC" code again. But holding the options and select buttons together for 5-10 seconds a second time caused the indicator lights to stop flashing, and allowed me to start the cycle.

unplug for 30 mins try again
