Article reference KA-01825
If T_Water error is displayed on the cylinder on its own accord, then the cylinder is indicating that the hot water temperature sensor appears to be misreading.
This will require a service visit to resolve.
It is recommended that the below parts are taken:
X-B1244096 Main PCB
X-B1244575 (temp probe 10kOhm 1200mm)
This applies to the Edel 170, 200 & 270 cylinders.
Note: It is impossible to ask for the backup to run if there is a T_Water fault as the hot water cylinder cannot safely energise the immersion element, if it cannot detect the current hot water temperature.
Note if you have your Edel set as a language other than English the error may display as -
SOND E EAU (French)
T_WA SSER (German)
SOND.ACQUA (Italian)
TEMP.WODY (Polish)
T_WA TER (Dutch)
T_AGUA_ER(Spanish)
T_VODA (Slovakian, Slovene, Czech, Croatian, Serbian)
SOND T.AR (Portuguese)
VANN TEMP (Norwegian)
VIZ HOM (Hungarian)
TEMP.EUJIT (Albanian)
