Error Codes

DISPLAY	CAUSE	PANEL BOARD CORRECTION
“E-4”	Control board overheating	Turn switch to OFF position, then turn switch back to ON; if “E-4” continues, the board is getting too hot; check for signs of overheating behind the control panel; once panel cools down the controls should return to normal; if “E-4” persists, have control panel replaced
“E-5”	Oil overheating	Turn switch to OFF position, then back to ON; if “E-5” continues, the heating circuits and temperature probe should be checked; once the unit cools down, the controls should return to normal; if “E-5” persists, have control panel replaced
“E-6”	Temperature probe failure	Turn switch to OFF position, then back to ON; if the “E-6” continues, the temperature probe should be checked; once the probe is repaired, or replaced, the controls should return to normal; if “E-6” persists, have control panel replaced
“E-41”	Programming failure	Turn switch to OFF position, then back to ON; if display shows “E-41”, the control should be re- initialized (See Programming Section) if the error code persists, have control panel replaced
“E-71”	Pump motor relay failure or wiring problem	Replace relay if contacts are stuck closed; check wiring on POWER/PUMP switch, or at wall receptacle; L1 and N may be reversed
“E-32, FAN FAIL ERROR, CHECK BLOWER, CLEAN DILUTIONBOX, CALL HENNY PENNY SERVICE”	Air pressure switch open; clogged dilution box or faulty blower; open drain switch; open high limit	Clean dilution box or replace blower if necessary; have drain switch checked; reset high limit or have high limit checked
