No water filling up in the dishwasher when programme set
When dishwasher switched on, you can hear the unit making nosises, however no water fills with in the unit. I have checked all pipe work and there seems to be no blockages. The dishwasher is only 2 years old

Re: No water filling up in the dishwasher when programme...
My instinct would be to replace the water inlet valve without even trying to prove whether that is the real problem. The valve is the plastic unit on the back wall of the cabinet that your cold water hose screws onto.
I think your dishwasher takes a Universal 90 degree Single inlet cold water solenoid valve, which you can find unbranded on the net for under £10.
Provided you remember to turn the power and water off before you start, there are no hidden surprises in the replacement procedure: Remove the inlet hose, undo the screws attaching the valve to the cabinet, unplug the two wires, unclamp and remove the hose inside the dishwasher, then reverse the process to reassemble. After assembly, check that the hose to valve coupling is watertight.
Granted, the problem might conceivably lie elsewhere, but the valve is so much more likely a culprit, so cheap to buy and so easy to fit that you might as well change it on spec.

If the pump is constantly running the easy way to check is to open the door and switch the appliance on if there is a noise than the anti flood system has been activated which means you either have a leak somewhere in the appliance or you have been visited by a rodent which loves to eat the polystyrene anti flood float the easy way to get your dishwasher working is to take off the rhs panel two screws torx t 20 lift off the top and then drain the water from the appliance in the space next to the motor housing this will get your dishwasher working but it wont fix the leak good luck that would need to be done by a pro is it can be complecated depending on where the leak is

You said you had water under the dishwasher,did you remove the lower panel below the door and check for water in the base frame as well. Bosch dishwashers have system in the base frame that detects water in base and cuts power off to every component except drain pump till it no longer sees the water in the base.
The water level detection is done via a small plastic pipe from the bottom of the machine that fills with water and causes the air pressure in the pipe to activate a micro switch in the water level detecter. The pipe can be disconnected at the bottom and gently blow into the pipe. If you listern carefully you can hear the micro switch click. The pipe must not be blocked and in some cases the switch contacts could be burnt. The water level is factory set but can be adjusted on the water sensor. Replace if necessary.
Washers have a (vacum pipe) that feeds a micro switch. The air pressure in the vacume pipe caused by the water filling the washer activates a vacum switch when the correct amount of water has entered the machiene. This vacum pipe could be partly blocked or the vacume pressure switch contacts burnt of faulty. This can be tested by physicaly blowing air by mouth into the pipe and you should hear the switch click.
The outlet pump is triggered by the anti flood micro switch via the polystyreene float on the base of the washer. If any water for whatever reason (leaky pipe)is on the floor the machiene automatically switches to pump out mode and only works once the water and the cause is rectified
First (I know this sounds bad but it does happen)check to see the tap is turned on (I have had where the owner thinks the tap is on and asked if I am nuts turns out the cleaning lady switched it off) If so turn off the tap and remove the inlet hose from the machine,there should be a filter in the unit where the pipe screws on this is more than likely blocked if so clean and replace pipe etc check on the tap side sometimes there is one there aswell clean if dirty,if there is still no water then we need to go deeper,the pressure switch could be fualty or there may be water in the pressure tube wich will tell the timer that the machine is full etc,I would however suggest you check the above first if you do not come right let me know and we can then investigate further.
There should be a float switch inside the dishwasher sometimes these get hung up on the full position which in turn keeps the solenoid from allowing the water to come on. remove the bottom rack and check to see if this is the case. Dislodging the float should fix the problem. If not listen to see if the solonoid Clicks when you turn the cycle to fill position if not it could be either solonoid or the timer. if you hear click and still no water check strainer in water line could be clogged or water is turned off some where.
turn the valves to the left if there the screw in type or parraell if the quick open type the first thing a dishwasher does when you start it is drain for a few minutes then stops then fills with hot water run the water as hot at the sink as you can before starting the washer there is a float in the tub that can shut the water valve off if its not seated on the safety switch after the drain at the start of cycles stops then you should hear the water valve open and start the fill let me know and we will go from there
you need to check the inlet walve . when you start the unit you say it drains. so after the drain do you hear the water entering the dishwasher? If you hear a sound like a buzzing noise that would be the inlet valve working. if thats the case there is a clog at the screen in the valve not allowing the water or enough water in the tub. seeing that this is a portable unit you will also want to check to make sure the fill hose is not kinked up anywhere in the cabinet or under neath the dishwasher. If you hear no buzzing noise you need to check the inlet valve with a meter to first make sure your getting power to it and that the valve itself if good. check these things out and let me know what you found and we can go from there
