3.1 Terms and definitions
3.1.14
Replace the entire entry by the following:
programme
series of operations which are pre-defined within the dishwasher and which are declared as
suitable for specified levels of soil and/or type of load
Note 1 to entry: Usually, an end of programme indicator signals the end of the programme and the user has access
to the load.
3.1.15
Add the note to entry after the definition:
Note 1 to entry: The cycle can be equal to or last longer than the programme.
3.1.16
Replace the definition by the following:
length of time beginning with the initiation of the cycle (of the selected programme), excluding
any user-programmed delay, until all activity ceases
3.1.17
Replace the definition by the following:
length of time beginning with the initiation of the programme, excluding any user-programmed
delay, until an end of programme indicator is activated and the user has access to the load
3.1.25
Replace the entire entry by the following:
end of programme mode
mode that begins immediately after the completion of the programme, and continues without
any further intervention from the user
Note 1 to entry: This mode can persist indefinitely or can be of limited duration if the dishwasher is equipped with
a power management system.
3.1.26
Replace the entire entry by the following:
left-on mode
mode that begins as soon as the dishwasher door has been opened and/or unlatched by the
user after the completion of the programme, and continues without any further intervention
from the user
Note 1 to entry: In some products, this mode can be equivalent to the off mode.
Note 2 to entry: This mode can persist indefinitely or can be of limited duration if the dishwasher is equipped with
a power management system.

3.1.27
Replace the entire entry by the following:
off mode
lowest power consumption mode of the dishwasher while it is connected to a mains power
source, achieved either automatically by the power management system of the dishwasher or
manually by switching it off using controls or switches on the dishwasher that are accessible
and intended for operation by the user during normal use
3.1.28
Replace the definition by the following:
mode where the user has selected and activated a specified delay to the commencement of the
cycle (of the selected programme) using a built-in function of the dishwasher
3.1.29
Replace the entire entry by the following:
end-of-programme mode duration
time from the start of end of programme mode until the dishwasher reverts automatically to
off mode
Note 1 to entry: This time span is only applicable to dishwashers equipped with power management systems.
3.1.30
Replace the entire entry by the following:
left-on mode duration
time from the start of left-on mode until the dishwasher reverts automatically to off mode
Note 1 to entry: This time span is only applicable to dishwashers equipped with power management systems.
Add the following new entry:
3.1.36
all activity ceases
power consumption decreases to a low steady state in which the power fluctuates by no more
than 10 % or 0,1 W, whichever is the greater, over a period of at least 60 min
Note 1 to entry: The current waveform shall be sampled at a frequency of 1000 Hz and averaged over the duration
of 60 s.
Add the following new entry:
3.1.37
intermittently recurring function
function that occurs during some, but not all, cycles of a specific programme (or programmes)
and that is directly related to water-softening operations, water-reuse operations or similar
operations and that alters water consumption, energy consumption and/or programme time for
the cycle
3.2.2
Add the following symbol after the symbol D :
T,i
D the target drying score of the reference machine

5.2 Sequence of test procedures and conditioning of the test machine
In the fourth line of the third paragraph, delete ", cycle time".
5.3.1.1 Voltage
In the second line, replace ±2 % with ±1 %.
5.3.2.1 Voltage
In the first line, replace ±2 % with ±1 %.
Add the following new subclause:
5.10 Intermittently recurring functions
5.10.1 Provision of information
Either the manufacturer or supplier shall provide information for all intermittently recurring
functions that relate to the programme selected for testing. This data shall include details of
changes to energy consumption, water consumption and programme duration that are caused
by each intermittently recurring function. The data shall also include a description of the
conditions that trigger each intermittently recurring function. An example of a format for
describing intermittently recurring functions is shown in Table V.1.
If no data is provided by the manufacturer or supplier, intermittently recurring functions may
take place during valid test cycles and, if this happens, it is likely that the measured and
averaged consumption values as well as the uncertainty of measurement will be significantly
higher.
The measured energy, water, and time of intermittently recurring functions can vary. If these
values differ by more than 10 % from the consumption values provided by the manufacturer,
then the laboratory should seek further guidance from the manufacturer.
5.10.2 Impact of intermittently recurring functions on reproducibility and the validity of
test results
When a dishwasher is tested over a test series of 5 to 8 test runs, intermittently recurring
functions may cause the results to be different to the true long-term average. For example, if
the dishwasher regenerates its softener every 3 cycles and uses a significant amount of water
to regenerate, the average water consumption for the test series would be higher if two
regenerations occurred than if only one occurred in the test series. Neither of these cases
would give the same result as the long-term average. Reproducibility of such a test would be
poor. Two options to resolve this problem are given in 5.10.3.
5.10.3 Treatment of intermittently recurring functions
For dishwashers with intermittently recurring functions, testing can be conducted according
to one of the following two options:
i) Excluding consumption data from test runs where the intermittently recurring function
takes place, from the calculation of the mean. In this case, testing shall follow the
procedures in Clause 8. This option should give reproducible results, but the values
determined will not account for the consumption associated with the intermittently
recurring function(s).
– 6 – IEC 60436:2015/AMD1:2020
© IEC 2020
ii) Extending the test series as necessary to include a suitable number of test runs where the
intermittently recurring function does not take place and a suitable number of test runs
where intermittently recurring function does take place. From such a test series,
consumption data for each case can be combined to give an appropriately weighted average
which would be representative of the long-term average. In this case, testing shall follow
the procedures in Clause 8 and Annex V. This option should give reproducible results and
account for the consumption associated with the intermittently recurring function(s).
