Table of Contents

In this section, you will find a description of the causes of common chemical reactions

which can occur between different types of soiling, process chemicals, and the compo-

nents of the machine, along with their remedies as necessary.

This section is intended as a guide. If unforeseen interactions occur during reprocessing or

if you have any queries on this subject, please seek advice from Miele.

General information

Problem

If elastomers (hoses and seals) and plastics

in the machine are damaged, for example

by swelling, shrinking, hardening, or brittle-

ness of materials, tears, and cracks, com-

ponents will not function correctly and this

generally leads to leaks.

A heavy build-up of foam during the pro-

gram sequence will impair the cleaning and

rinsing effect on the wash items. Foam es-

caping from the wash cabinet can cause

damage to the machine.

When foam develops, the cleaning process

is not standardized or validated in principle.

Corrosion to stainless steel in the wash

cabinet and to accessories can give them a

different appearance:

- rust (red stains/discoloration)

- black stains/discoloration

- white stains/discoloration (etched surface)

Corrosive pitting can lead to the machine

not being water-tight. Depending on the ap-

plication, corrosion can affect cleaning and

rinsing results or cause corrosion to (stain-

less steel) wash items.
