Checking and Cleaning the Water Strainer
(Monthly) DFW/DFWT/DFWF-200/250 Only
The Water Strainer protects your equipment from any
foreign debris in the water line that could damage the
unit’s solenoid (causing the unit to leak/flood)
To ensure proper and consistent steaming results,
check the Water Pressure Regulator (Figure 12) and
Strainer Cup regularly. If the pressure on the gauge
has dropped, check the Strainer Cup and clean out the
accumulated debris as follows:
1. Shut off the water supply valve to the unit,
unscrew the Strainer Cup, and carefully remove
