Water Sensor Cleaning

It  is  required  that  the  water  sensor  be  cleaned  at  least  once  per  week. 
Cleaning  the  sensor  will  ensure  that  the  water  level  in  the  chamber  is 
properly reported to the microprocessor all during the cycle.

The water sensor is located in the rear of the chamber. It is easily cleaned 
using a damp cloth or sponge, you may use a mild soapy solution if you 
like.  It  is  important  to  wipe  the  sides  of  the  sensor  as  well  as  the  tip,  to 
remove any dirt or debris that may have built up.
