Solution
Fill tanks with material.
Replace Brushes. See
System Repair manual.
Use a USB drive and
download all logs.
Turn on the heat and allow
the hose to reach the
setpoint before turning on
the pumps.
Verify the ADM pressure
reading the analog gauges
at the manifold. Replace
transducers if they do not
match.
Ensure rotary switch on
MCM is set to position 0 for
E-30i.
Check to ensure the
pressure transducer is
properly installed and
all wires are properly
connected.
See if the error follows the
transducer. Disconnect
transducer cable from
#8 and #9 connectors
on MCM. Reverse A
and B connections and
check if the error follows.
If the error follows the
transducer, replace the
pressure transducer. See
system repair manual. If
the error does not follow,
replace MCM. See system
repair manual.
