Aquarius dwf50 fault?

ONLY TO BE CARRIED OUT BY A COMPETENT ELECTRICIAN or person
Please unplug or isolate appliance from electrical mains and remove the fuse before attempting any sort of service or repair to this machine!

Tool required
1: Plunger
2: Warm soapy water
3: + bladed screwdriver
4: multi meter
5: soldering iron please note soldering irons get very hot and not to be left unattended!

1: Fill with warm soapy water then plunger down where the filters fit in, take the filers out at the bottom of the machine don't be to rough with it when you push down its plastic, use more pulling force you are looking for signs of residue if blocked keep plunging with warm water if you see reside repeat process till water is clean

Clean all filters with warm soapy water and a nylon bristle pan brush,
Put filters back in and try the machine and remember you have to plug it in or put fuse back into isolation switch reinsert the fuse and switch back on
if this fails then repeat mains disconnection and move on to #2

2: TURN OFF the appliance isolation tap connecting to the cold water inlet check all the inlet filers on the machine and the tap IE the cold water in pipe.
if not blocked with limescale then move to reconnection of the cold water inlet pipe move on to #3
if filters are blocked a new inlet filter will have to be purchased type it into a search engine and search for a good deal if you look around :)

3: Remove the front handle at the top of the door unscrew the screws located at the back edge inside door panel once screws removed from handle there will be two circuit boards as you look down on them one to the left long rectangle and the second to the right a square control board with a lot of wires coming from it running around the door

Now you have to look at the circuit to the right the control board this is where you might find your fault its a diode on the board just behind the black relay component next to the blue component you should be looking at the small signal diode its orange bronze looking http://www.jrhackett.net/images/1N4148.jpg
you will find it on the opposite side of the circuit board you will have to unscrew this board in order to see the components use a multimeter and switch to continuity test.
Continues beep = diode is damaged.
un-solder the component take to electrical spare and repairs store and seek the component.
If no sound the diode is ok and the relay may need to be checked for damaged contacts or a fault in the coil ie solenoid if this is so un-soldering is needed
and a replacement part sourced
once part have been replaced check for further damage with the meter ie broken or burned out tracks on the board
If all looks to be sound reassemble the door handle in reverse order to undoing it once done reconnect the electricity ie plug back in or reinsert the fuse on the isolation switch and switch back on and try to run machine

if you cant be bothered with this part then find a cheap control board supplier if its not this part you need send it back to them or call a qualified service technician ;) to source the part for you at a price best to look online directories

hope this helped
