Summary
Newmar
has decided to incorporate a system reset switch for coaches equipped with HWH hydraulic entrance steps. The switch has been added to the front overhead cabinet during production on later 2018 models. If the HWH system fails to operate the pump assembly when using the leveling system touchpad, slideout switches, or the entrance step, this reset switch will provide the coach owner with a more convenient location for resetting the HWH system. This will eliminate the need to pull the F-11 fuse or exit the coach to turn off the chassis disconnect in the event of a system lockout. Issue: In the event of a step failure, the person(s) inside the coach would have a large gap between the door threshold and the ground. The person(s) may have to exit via the large gap or the emergency exit door to get out of the coach.

Description
Newmar has decided to incorporate a system reset switch for coaches equipped with HWH hydraulic entrance
steps. The switch has been added to the front overhead cabinet during production on later 2018 models.
If the HWH system fails to operate the pump assembly when using the leveling system touchpad, slideout
switches, or the entrance step, this reset switch will provide the coach owner with a more convenient location
for resetting the HWH system. This will eliminate the need to pull the F-11 fuse or exit the coach to turn off
the chassis disconnect in the event of a system lockout.
Issue: In the event of a step failure, the person(s) inside the coach would have a large gap between the door
threshold and the ground. The person(s) may have to exit via the large gap or the emergency exit door to get
out of the coach.
Correction: A reset switch and label will be installed in the front overhead cabinet.
Refer to the attached population list for the affected coach and VIN numbers.
Recommended Action
Call your Service Account Manager to obtain authorization and order the parts. Follow the attached work
instructions to complete the reset switch installation and testing.
