4 _ Safety Instructions
CAUTION
AFTER SERVICING
• Ensure that all components are reassembled correctly and are safe before connecting the appliance to the mains supplies.
4
Ensure all electrical safety tests are carried out, before and after any work is carried out on the appliance.
• To comply with the requirements of European standard.
BS EN-50678 20:20 published 12th March 2020 Engineer Responsibilities.
This procedure is compulsory and must be completed on every service visit or repair to ensure safety of the appliance, the
service engineer, customer and comply with European standard BS EN-50678 20:20
EN EN50678:2020, General procedure for verifying the effectiveness of the protective measures of electrical equipment after
repair.

: Function Test
Test meter required specifications
Socket tester,
polarity and earth
The test current within the measuring range between
0.2 Ω and 1.99 Ω shall not be below 200 mA.
-
Measuring of
protective bonding
(Earth continuity)
Measuring range between 0.2 Ω and 1.99 Ω test current
shall not be below 200 mA.
Using test equipment according to EN 61557-4 or EN
61557-16 will fulfil this requirement.
Insulation
resistance
The value of the test voltage of the test equipment shall
not be below 500 V DC for a test current of 1 mA.
Using test equipment according to EN 61557-2 or EN
61557-16 will fulfil this requirement.
Earth leakage
resistance
For measuring protective earth leakage current the
measurement range shall include the values 0.25 mA
up to 19 mA.
Measuring device shall be in accordance with 670
EN 61010-1:2010, Annex A or or EN 62353:2014, C.4.
• Check whether the washing machine is level in relationship with the floor. Check whether it is
installed firmly on the floor.
