Important
It is recommended to use the program “P” when first using the “KWT” washing system. In this
way the air inside the peristaltic pumps and the detergent and rinse aid tubes is removed, thus
assuring correct system operation. When cleaning is completed leave the oven door slightly open.
Warnings
Do not open the door during washing operations, as chemical substances used for cleaning and
hot fumes might escape. Danger of corrosion and burns! When the red screen signalling
temperature in the cooking chamber exceeding 100°C, washing cannot be activated. It is possible
to go back to the overview screen by pressing the “SELECT” key.
Only for mod. EKF 1664 TC e mod. EKF 2011 TC (wheeled models) perform the
automatic
cleaning cycle
with the internal door glass in position: “glass down” (paragraph 4.3.2.1)
When operating in the “WASHING MENU” the WARNING and ALARM SCREENS (flashing/sound)
are not RED but BLUE.
Before starting a cooking cycle ensure there are no detergent residues in the chamber that has just
been washed. Any residues must be removed with a moist cloth suitably protecting your hands,
eyes and mouth, and the cooking chamber must be thoroughly rinsed.
8.3 Cleaning fans
The fans must be regularly cleaned with appropriate descaling products. All their parts must be
thoroughly cleaned, eliminating any limescale. The fan cover must be removed to access fans.
When cleaning is completed fit the cover back on operating in reverse order.
8.4 Door gasket cleaning
For hygienic and functional reasons it is good practice to clean the door gasket at the end of every
day the oven is used. It must be accurately washed with warm soapy water. It must be rinsed and
dried with a soft cloth. Any scaling or food residue must be removed with special care, without
using sharp metal tools that might irreparably damage the gasket.
8.5 Door cleaning
The internal glass of the cooking chamber door may be cleaned using the same type of degreaser
used for manually cleaning the cooking chamber; otherwise, a normal (non toxic) glass cleaning
product may be used. A common glass detergent may be used also to clean the external door
glass. In any case one may simply use warm soapy water. After rinsing dry the glass surface well
with a soft cloth. Should opaque spots form between the two glass panes, these may be removed
as they are inspectable.
8.6 Cleaning the external casing
The outer steel surfaces must be cleaned with a cloth soaked in warm soapy water or mixed with
a little vinegar, they must be rinsed well and dried with a soft cloth.
Should you wish to use specific products on the market, these must comply with the cleaning
requirements set out in the “General information” paragraph (paragraph 8.1).
It is worth remembering that the counter supporting the appliance or the floor surrounding the
area where the appliance is should also be cleaned without using acid corrosive substances (e.g.
muriatic acid) since the vapours released by them might corrode and deteriorate the outer steel
shell and cause irreparable damage to the electrical components inside the appliance.
8.7 Inactivity period
Should the appliance not be used for a long extent of time, it is good practice to disconnect it
from the power (act on the safety magnetic circuit breaker located upstream of the appliance) and
water supply. It is recommended to clean it with care internally (cooking chamber) and externally,
