Maintenance before start up of a test series
In order to ensure that the reference machine is in good order and will
work in accordance with the specifications given in IEC 60456 a number
of checks can be carried out:

Before any major test period:

• Check for any lint according to instructions in Chapter 8.
• Check the supply time for first fill. Shall be 114 ± 14 seconds from
closure of door lock relay to end of filling of the 5 litre valve. If the time
is too short, lower the water pressure. If the time is too long, clean the
supply filter in accordance with the instruction set out in Chapter 8 or
increase the water pressure.
• Carry out an installation check according to instructions in Chapter 3.
• Carry out a weight check according to instructions in Chapter 5.
• Carry out an empty run test. Use Cotton 60ºC or Cotton 40ºC depen-
ding on the type of program to run be run during the test period.
• Compare the results obtained with results shown in Table 1 in Chapter
9 "Empty run test data". Note the definitions assigned to the time inter-
vals shown in the table.
• If the value fall outside the specification detailed in Table E.2 in IEC
60456, carry out a second empty run test or recalibrate.
• If other values obtained from the empty run test differs from the value
in Table 1, analyse the reason for this difference and correct (wrong
water pressure, wrong supply water temperature, faulty heating ele-
ment etc).

Before every test period:

• Check for the presence of lint according to instructions in Chapter 8.
• Check the supply time for first fill. Shall be 127 ± 14 seconds from
closure of door lock relay to end of filling of the 5 litre valve. If the time
is too short, lower the water pressure. If the time is too long, clean the
supply filter according to instruction in Chapter 8 or rise the water pres-
sure.
• Carry out a weight check according to instructions in Chapter 5.

Daily check:

• If the machine has not been in use for the last 2 hours run the start up
program (Program 991).The start up program will flush the machine
with water and normalise all temperatures inside the machine.
