Error Code tE5

Steam water supply pump failure detected in test mode

How to Fix

1. 1

   Enter diagnostic test mode (Power on, then More Time + Less Time simultaneously for 0.5 sec).

2. 2

   Press START/PAUSE four times to reach the pump test step — allow each step to complete before advancing.

3. 3

   Observe the AD value on the display: if higher than 10, pump is normal.

4. 4

   If AD value is 10 or below, E5 error will display indicating pump failure.

5. 5

   Check connection between harness wire and pump connector for loose or broken pins.

6. 6

   Verify 12 VDC is supplied to pump valve (coil resistance should be 240 Ω ±10%, limit current 550 mA).

7. 7

   If connections are good and voltage is present, replace the DC water supply pump.
