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rstll.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specication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rstll.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:

with water and normalise all temperatures inside the machine.
