panel and the electrically-controlled box has
become loose.
2. Change a plug board
3. Replace cable
Water leakage
1. The water pipe connector is loose or broken

DELUXE KEYPAD ERROR CODES
Error Code
Problem
Solution
E1
Water level sensor failure
Check the cable connection to the water level sensor. If it’s not loose, replace water level sensor.
E2
Temperature sensor short circuit
Replace the keypad.
E3 Temperature sensor open circuit
Check the temp sensor cable connection from keypad to the temp sensor cable. Make sure cable
connection is ok.
E4
No water in the tank within 4
minutes
Check whether the water inlet pipe is blocked. If no problem, check whether the water inlet valve is
jammed. If the water inlet valve is jammed, clean the net inside the water inlet valve or replace it.
E5
Communication failure between
steam generator and keypad or
between both keypads.
Single keypad: Check cable connections at both ends of cable. Make sure the pins on both ends of
the cable are not bent or broken. If bent or broken, the cable will need to be replaced.
Dual Keypad: If E5 shows on sub-keypad, check cable connection between both keypads. If E5
shows on both keypads, check the control cable connection between steam generator and main
keypad. If the pins on either cable are bent or broken, cable will need to be replaced.
