The reference machine shall at a regular basis be maintained and checked
in order to ensure that the reference machine is in good order and will

Every 6 months:
• Use the start up program (Program 3) and make a visual check and
ensure that the supply or drain valves are not leaking.
• Carry out a flow meter check according to instructions in Chapter 18.

• Carry out an empty run test Cotton 60ºC or Cotton 40ºC depending
what type of program to run during the test period.
• Compare the results obtained with results shown in Table 1 in Chap-
ter 11 "Empty run test data". Note the definitions assigned to the time
intervals shown in the table.
• If values are outside the specification in Table E.2 in IEC 60456 make
another empty run test or recalibrate.
• If other values from the empty run test differs from the values shown in
Table 1, analyse the reason for this difference and correct (wrong water
pressure, wrong supply water temperature, faulty heating element etc).
• To prevent the build-up of scale if the reference machine is run in
hard water decalcify the machine according to procedure described in
chapter 21.
• Check for any build-up of lint or detergent and, if verified, clean in ac-
