If you have .d0 error code most if the time what it is is a blocked filter insid the dishwasher.

Remove the bottom basket and take out the metal mesh filter at the bottom and turn this over and have a look on the underside.

If this is covered in slime you need to give it a good clean out.

As what happens is the mesh filter slimes up and causes the dishwasher to overfill with water and the safety pressure switch kicks in and this stops the heater from activating so that is why it wont heat.

Check that filter and see what you find. As to be honest most for the time for that error code its the filter that slimes up that causes this.

Once cleaned try it on a fast wash as this will fill with water and should start to heat up stright away from there.

Try that first and see what you find and let me know.
