specifically for the Miele G590 and the Miele G595 4) applicable to any suitable reference machine that complies with Annex E M.2 Background In order to get repeatable and reproducible performance from the reference dishwasher, it is important that the water consumption be carefully monitored and adjusted periodically so that its average total water consumption during the Universal programs (or those with fills) are as close close as as possible possibletotothethe target water consumption of 27,5 27,8l l(this target water consumption of (thisincludes includes the the water consumed in the regeneration operation at the start of each program) Although the reference dishwasher uses a pressure switch to stop overfilling, each fill is controlled primarily by a timer Therefore the flow rate of the water into the dishwasher (and hence the fill volume) is affected by the water pressure at the dishwasher inlet Each reference dishwasher is supplied with a pressure control valve which must be installed and which should be used to adjust the inlet pressure so that the fill volume is as close as possible to the target volume If the laboratory supply pressure varies from day to day, it may be necessary to also adjust the inlet pressure reduction valve on the reference dishwasher to compensate for these changes This aspect of the reference machine performance needs ongoing monitoring M.3 Target values Experience has shown shown that thatto toachieve achievethe thetarget targetvolume volumeofof 27,8 in the reference machine on 27,5l l in the reference machine a (e.g Gentle, Universal), the the fill volumes will will be approximately as follows: on4 afill4 program fill program (e.g Gentle, Universal), fill volumes be approximately as follows: (a) regeneration: (b) pre-wash, main wash, rinse 1, rinse 2: l l 3,15 3,05 four fills of of 6,16 l each 6,11 l each Measurements on a number of reference dishwashers suggest that the regeneration operation is generally around 11,1 % to 11,3 % of the total water consumption volume for fill programs However, this can be slightly higher or lower, depending on the machine under test and the particular run Each fill volume typically varies by less than 50 ml when inlet pressure conditions are stable (again this depends on the machine to some degree) Fill volume variations (when measured in ml) for the regeneration operation are similar to other operations, so this operation appears slightly more variable (in relative terms) than other operations Initial adjustment can be made by allowing the dishwasher to progress through a regeneration single fill filloperation operation(pre-wash) (pre-wash)ononthe theselected selected program The total water volume cancan be and aa single program The total water volume be estimated

that the dishwasher is close to the target, the total volume should be confirmed with a full cycle on the selected program (using a load with no detergent as specified in Annex E) The fill volume should be largely unaffected by the presence of soil or detergent in the load _ 4) Miele G590 and Miele G595 are the trade names of products supplied by Miele This information is provided 4) Miele

annex sets out the determination of off mode power, left on mode power and delay start mode power The first two are steady state modes that can persist for an indefinite period while delay start mode is a short duration mode associated with active mode (selection and use of a particular programme) These are the only three low power modes specified in this European Standard Other low power modes may exist in some products, but for the current designs of dishwashers, these are not considered important in terms of duration and energy consumption Where Low Power Modes are determined, they shall be determined in accordance with this clause Ensure that the following conditions remain relevant for the duration of the measurement: • instructions for use regarding installation, operation and settings of the dishwasher (as applicable) are followed; • the appliance shall be connected to mains power for the duration of the test; • no adverse warning indicators (including rinse aid and salt indicators, where applicable) are present (normally no lights or indicators are active in this mode); • laboratory supply water is left on at the specified pressure; • ensure that no network is connected to the product; • follow manufacturer’s instructions regarding the configuration of the dishwasher when there is no network present (where applicable) Power measurements for left on mode, off mode and delay start mode shall be made in accordance with the requirements of EN 50564:2011 except for 5.3 “Procedure” The measurement procedure and measurement duration is specified in this Annex O The average power is measured in watts and rounded to second decimal place Data for the required parameters, power and energy consumption, shall be recorded at regular intervals of s or less throughout the test using a data logger or computer BS EN 50242:2016 EN 50242:2016 (E) 60436 © IEC:2004+A1:2009 EN 60436:2016 (E) +A2:2012 – 68 – Figure O.Z1 – Measurement procedure for the low power

a power management system in Figure O.Z1 For appliances with no power management system or with a power management that activates in more than 30 min, off mode is determined when the dishwasher is switched off by the system that activates in more than instructions 30 min, off For mode is determined when management the dishwasher is user in accordance with manufacturers’ appliances with a power system switched off by the user in accordance with manufacturers’ instructions For appliances with that activates in 30 or less, off mode is determined after the dishwasher automatically reverts to a off power management system that activates in 30 or less, off mode is determined after the mode dishwasher automatically reverts to off mode In all cases, off mode shall be determined over a period of not less than 10 In all cases, off mode shall be determined over a period of not less than 10 The power consumption of the off mode is the average of the measured data The power consumption of the off mode is the average of the measured data O.3 Determination of left on mode power At the completion of any programme the door of the dishwasher is opened within and the measurement shall begin immediately For determination of this mode, no additional action is 40 – 69 – BS EN 50242:2016 60436 © IEC:2004+A1:2009 +A2:2012 taken by the operator to switch off the dishwasher (i.e not initiate off mode) after the door has been opened The door remains unlatched during the measurement The procedure is explained in Figure O.Z1 NOTE 1 This procedure is not applicable where the user has to turn off the product before the door can be opened NOTE 2 For a dishwasher, the term unlatched means the door is closed as far as possible without engaging the latch For machines without power management system (where left on mode persists for an indefinite period), the measurement of left on mode shall be determined over a period of 30 In this case the left on mode average power is reported When the test machine is equipped with a power management system that automatically reverts to off mode but the time to activation of the power management system is longer than 30 min, the measurement of left on mode phase shall be determined over a period of 30 In this case the product is noted as having a power management system that activates in >30 and only the left on mode power is reported When the test machine is equipped with a power management system that automatically reverts to off mode and the time to activation of the power management system is 30 or less, the measurement of left on mode shall be determined over the actual duration In this case the left on mode power and the left on mode duration are reported The power consumption of left on mode is the average of the measured data O.4 Determination of delay start mode power For determination of this mode, any programme can be selected and a user programmed delay of hours (or as close as possible to hours if hours cannot be selected) is selected by the operator The average power consumption during this period is determined Latch the door and keep it latched for the duration of the test Select any programme to be measured and programme the delay start period Power measurements in delay start mode shall commence from the moment the delay start mode is activated and shall continue until the programme starts The programme name selected shall be stated with the measured power value Where the display changes during the timer countdown, there may be some small variations in power consumption during this mode NOTE For a dishwasher, the term latched means that the door is closed and the door interlock is engaged so that the product could operate if required The power consumption of the delay start mode is the average of the measured data Text deleted O.Z1 Determination of left on mode duration If a test dishwasher is equipped with a power management system to revert the machine automatically to off mode the left on mode duration is determined in accordance with this clause At the completion of any programme the door of the dishwasher is opened within and kept unlatched during the measurement which shall begin immediately For determination of the left on mode duration, no action is taken by the operator to switch off the dishwasher (i.e not initiate off mode) The time measurement of the left on mode duration is started immediately until the machine reverts automatically to the off mode The dimension of the measured time is given in minutes and is rounded to the nearest minute BS EN 50242:2016
