Electrolux Professional dESC

What does Electrolux Professional dESC mean?

dESC tells you the SkyLine oven's boiler needs descaling because the scale build-up parameter has been reached. For cycles that need the boiler, the oven stops until you descale. It is a maintenance demand rather than a fault: the oven is protecting the boiler from limescale that would otherwise reduce performance and cause over-temperature alarms.

Symptoms

• dESC displayed
• Boiler-dependent cycle stops
• Prompt to descale the boiler
• Possible reduced steam quality beforehand

Common causes

• Scale in the boiler; parameter bSCu has been reached

Diagnostic steps

1. 01

   Run a cleaning program

   Run a cleaning program that includes the rinse and descale cycle.

2. 02

   Use the specified tablets

   Use 2 C25 tablets only for the descale cycle as directed.

3. 03

   Follow water-hardness intervals

   Descale at the intervals appropriate to your water hardness to prevent recurrence.

4. 04

   Resume cooking

   Once descaling completes, boiler cycles can be used again.

5. 05

   Call Service if it persists

   If the problem persists after descaling, call Service.

When to call a professional

dESC is a routine descale demand that staff can usually action with the specified tablets. Call an Electrolux Professional engineer only if the alarm persists after a correct descale, which suggests the descale cycle is not clearing the scale or a sensor is misreading the build-up. Persistent scaling problems can lead to boiler over-temperature faults, so professional water-treatment advice may be needed.
