Miele f63 fault. I poured clean water through the soap dispenser drawer and tipped the washer at 45° several times and it's working now.

I am assuming its a bosch, F63 indicates a failure with the main control board can try to reset the machine but if it does not work you will need to replace the board. Try this:
Turn the knob to off and now shut the door. Turn the knob to the 6 o'clock position and wait for two seconds. Start/pause should flash. Now press and hold the spin button and turn the knob to 7 o'clock position. Release the button and turn the unit off. Did the fault erase? Try unit again.
If did not help you need to replace the main control board.
Again I don't know machine model but error 15 Fault: No pump out detected. Check pump outlet hose and sump/filter for blockages

Need to know brand of machine?

Depending on the model number - (guessing its a W48XX series) F63 is a water path fault - This is the control unit that directs the water flow to the proper path (pre-wash, detergent, fabric softener ect..... ) Sometimes and audible clicking can be heard when this unit fails as it trying to switch to the proper path as per the program being ran.

The F63 is an error when something is blocking in the water path. I would suggest to open the front access drain flap and check for any objects like pins, coins etc. remove them and this should clear the error.

heres your problem..

3.33 Fault code F63, water path control unit In normal operation mode the display shows Technical fault. The Check inlet LED flashes rapidly. The programme is interrupted. The drain pump is activated for 120 s. Cause Water path control system faulty. The power-programme module (ELP) cannot register a valid position of the water path control unit within approx. 80 s of it being switched on.
Note: Water intake monitoring is not active if a valid position of the water path control unit cannot be registered.

Remedy Check the water path control system. Check the water path control system circuit for an open or short circuit, and correct insulation.

Mine is W3844. Miele's technician said the Wather Path Control Unit (part # 6271992) need to be changed.
Total Cost: (HKD)
450 for todays check cost
1100 for the part
250 for the labour to change the part.
