Make sure the path of the step is clear. Pressing the
override switch disables the curb and shin guard sensors.
Stop the step before it contacts any objects or the ground.
Failure to do so may result in severe damage to the step or
contacted objects. Using the override switch will extend the
step during switch activation at any time unless the park
brake is released. Releasing the park brake will disable the
override switch.

Reset Switch
When equipped, this switch is located in the overhead
cabinet (may be above the main control panel) and is
labeled “HWH Master Reset Switch.” In the event the
HWH system is inactive, press and hold the reset switch
for five seconds. Then release the switch, and attempt
system operation again.
PROBLEM
This article provides troubleshooting tips for the following
components:
•
HWH hydraulic slideouts
•
HWH hydraulic generator slideouts
•
HWH hydraulic entrance steps
•
HWH hydraulic leveling jacks
If any, or all, of these HWH hydraulic components are
not functioning, follow the troubleshooting steps before
contacting Newmar or HWH.
SOLUTION
If the pump runs for an accumulative time of
approximately three minutes while operating the HWH
jacks, slideout(s), generator slideout, or the step, the
system will turn off and the pump will stop running. This
only applies to coaches equipped with an HWH step.
If for some reason the pump doesn’t run for any HWH
equipment, it might be necessary to reset the HWH
system. If this time lockout occurs, power for the HWH
control system must be removed before any system
components will function.
Coaches Equipped With HWH
Reset Switch
Current coaches equipped with an
HWH step system also have an HWH
reset switch installed in the main
control panel, allowing the user to
reset the HWH control board.
1. Press and hold the momentary
contact switch for approximately
five seconds to reset the system.
Coaches Not Equipped With
HWH Reset Switch
1. There is a five (5) amp blade fuse for the HWH system
in the driver-side front electrical compartment. Refer
to the image for this fuse’s location (F11).
2. Remove this fuse for approximately five seconds, and
then reinstall the fuse.
3. The systems should now function; however, if the
system still does not function, contact Newmar
Corporation or HWH Corporation for further
assistance.
