Bob, according to the service manual there are a few possibilities
Sud - SUDS LOCK (Overdose of Detergent detected during the Wash Cycle)
The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If “Sud” is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.
• If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
• Check the drain hose and make sure it is not plugged or kinked
• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
• Check/ Clean Drain Pump Filter of foreign objects
• Check Drain Pump
• Check the Pressure Switch
• Check CCU
So check on that for the Suds error. For the not draining, it might be a clogged pump or hose. It is entirely possible that small objects to get into the water drain system and clog the hose or the pump. Remove the hose from the pump and the drain plug from the filter at the water pump and clean it out.
1. Take off the lower front panel.Remove the bottom front access panel just remove the 3 Torx screws on front bottom of machine. Slightly lift the panel and pull the bottom towards you
2. Turn the pump filter cover counter-clockwise by hand and remove. Place a bucket or pan underneath it since you will get the water spilling out of there. Removing the filter should remove all water from your washer.
If the washer still won't drain water the drain pump might be defective. Get the service manual from here to review your diagnostics codes and for a possible replacement of the drain pump if required. Hope this helps, good luck.
