Power-Out Compensation Function; Power-Out Compensation Function Process; Water Heater Error Function - Samsung WF-F1256 Service Manual

8) Power-out compensation function

● If power is out on selected process, the process before power out is stored to EEPROM, once power is
back the process before power out continues.
● When power is back, washing process starts from the process at the point of the power out, rinse/drain
process starts from the initial process.

9) Water heater Error function

① This function starts working, when the heater works abnormally.
(this function begins sensing the heater 2 minutes later, after the heater operating)
② The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes
(Y=A2-A1)
- For 10 minute late, the variance of temperature(Y) is less than 2 ℃ , "HE2"message is displayed on the
panel.
③ The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 11 minutes
(Y=A2-A1)
- For 1 minute the variance of temperature(Y) increases more than 40 ℃ , "HE1"message is displayed on
the panel.
④ At this time heater, Error "HE2 (heater do not work), HE(overheated)" is displayed and all working
process off
⑤ The heater operating continues during heating hours, if washing hour is left over, the residual washing
process keeps going without heating.
