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 21.
• Check the supply time for first fill. Shall be 109 ± 14 seconds from closu-
re of door lock relay to end of filling. If 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 21 or increase the water pressure.
• Carry out an installation check according to instructions in Chapter 13.
• Carry out a flow meter check according to instructions in Chapter 19.
• Carry out an empty run test. Use Cotton 60ºC or Cotton 40ºC depending
on the type of program to be run during the test period.
• Compare the results obtained with results shown in Table 1 in Chapter
23 "Empty run test data" MP-Lab. Note the definitions assigned to the
time intervals 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 element etc).
Before every test period:
• Check for the presence of lint according to instructions in Chapter 21.
• Check the supply time for first fill. Shall be 109 ± 14 seconds from clo-
sure of door lock relay to end of filling. If the time is too short, lower the
water pressure. If the time is too long, clean the supply filter in accordan-
ce to instruction in Chapter 21 or rise the water pressure.
• Carry out a weight check according to instructions in Chapter 19.
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.
