COMMISSION DELEGATED REGULATION (EU) No 1059/2010  
of 28 September 2010  
supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to 
energy labelling of household dishwashers  
(Text with EEA relevance)  
THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European 
Union,  
Having regard to Directive 2010/30/EU of the European 
Parliament and of the Council of 19 May 2010 on the indi ­
cation by labelling and standard product information of the 
consumption of energy and other resources by energy-related 
products (  1 ) and in particular Article 10 thereof,  
Whereas:  
(1) Directive 2010/30/EU requires the Commission to adopt 
delegated acts as regards the labelling of energy-related 
products representing significant potential for energy 
savings and having a wide disparity in performance 
levels with equivalent functionality.  
(2) Provisions on the energy labelling of household dish ­
washers were established by Commission Directive 
97/17/EC of 16 April 1997 implementing Council 
Directive 92/75/EEC with regard to energy labelling of 
household dishwashers (  2 ). 
(3) The electricity used by household dishwashers accounts 
for a significant share of total household electricity 
demand in the Union. In addition to the energy efficiency 
improvements already achieved, the scope for further 
reducing the energy consumption of household dish ­
washers is substantial.  (4) Directive 97/17/EC should be repealed and new 
provisions should be laid down by this Regulation in 
order to ensure that the energy label provides dynamic 
incentives for suppliers to further improve the energy 
efficiency of household dishwashers and to accelerate 
the market transformation towards energy-efficient tech ­
nologies.  
(5) The information provided on the label should be 
obtained through reliable, accurate and reproducible 
measurement procedures, which take into account the 
recognised state-of-the-art measurement methods 
including, where available, harmonised standards 
adopted by the European standardisation bodies, as 
listed in Annex I to Directive 98/34/EC of the 
European Parliament and of the Council of 22 June 
1998 laying down a procedure for the provision of 
information in the field of technical standards and regu ­
lations and of rules on Information Society services (  3 ). 
(6) This Regulation should specify a uniform design and 
content for the label for household dishwashers.  
(7) In addition, this Regulation should specify requirements 
as to the technical documentation and the fiche for 
household dishwashers.  
(8) Moreover, this Regulation should specify requirements as 
to the information to be provided for any form of 
distance selling, advertisements and technical promo ­
tional materials for household dishwashers.EN 30.11.2010 Official Journal of the European Union L 314/1  
( 1 ) OJ L 153, 18.6.2010, p. 1.  
( 2 ) OJ L 118, 7.5.1997, p. 1.  (  3 ) OJ L 204, 21.7.1998, p. 37.(9) It is appropriate to provide for a review of the provisions 
of this Regulation taking into account technological 
progress.  
(10) In order to facilitate the transition from Directive 
97/17/EC to this Regulation, it is appropriate to 
provide that household dishwashers labelled in 
accordance with this Regulation are to be considered 
compliant with Directive 97/17/EC.  
(11) Directive 97/17/EC should therefore be repealed,  
HAS ADOPTED THIS REGULATION:  
Article 1  
Subject matter and scope

Verification procedure for market surveillance purposes  
For the purposes of checking conformity with the requirements laid down in Articles 3 and 4, Member State authorities 
shall test a single household dishwasher. If the measured parameters do not meet the values declared by the supplier 
within the ranges set out in Table 1, the measurements shall be made on three more household dishwashers. The 
arithmetic mean of the measured values of these three household dishwashers shall meet the values declared by the 
supplier within the range defined in Table 1, except for the energy consumption, where the measured value shall not be 
greater than the rated value of  E t by more than 6 %.  
Otherwise, the model and all other equivalent household dishwasher models shall be considered not to comply with the 
requirements laid down in Articles 3 and 4.  
Member State authorities shall use reliable, accurate and reproducible measurement procedures, which take into account 
the generally recognised state-of-the-art measurement methods, including methods set out in documents, the reference 
numbers of which have been published for that purpose in the  Official Journal of the European Union .

Method for calculating the Energy Efficiency Index, the Drying Efficiency Index and water consumption  
1. CALCULATION OF THE ENERGY EFFICIENCY INDEX  
For the calculation of the Energy Efficiency Index ( EEI) of a household dishwasher model, the annual energy 
consumption of the household dishwasher is compared to its standard annual energy consumption.  
(a) The Energy Efficiency Index ( EEI) is calculated as follows and rounded to one decimal place:  
EEI ¼ AE  C 
SAE  C Ü 100  
where:  
AE  C = annual energy consumption of the household dishwasher;  
SAE  C = standard annual energy consumption of the household dishwasher.  
(b) The annual energy consumption ( AE  c ) is calculated in kWh/year as follows and rounded to two decimal places:  
(i) 
AE  C ¼ E  t Ü 280 þ Ï 
P o Ü 525 600 – ðT t Ü 280Þ 
2 þ P l Ü 525 600 – ðT t Ü 280Þ 
2 B 
60 Ü 1 000  
where:  
E t = energy consumption for the standard cycle, in kWh and rounded to three decimal places;  
P l = power in ‘left-on mode’ for the standard cleaning cycle, in W and rounded to two decimal places;  
P o = power in ‘off-mode’ for the standard cleaning cycle, in W and rounded to two decimal places;  
T t = programme time for the standard cleaning cycle, in minutes and rounded to the nearest minute;  
280 = total number of standard cleaning cycles per year;  
(ii) Where the household dishwasher is equipped with a power management system, with the household dish ­
washer reverting automatically to ‘off-mode’ after the end of the programme,  AE  C is calculated taking into 
consideration the effective duration of ‘left-on mode’, according to the following formula:  
AE  C ¼ E  t Ü 280 þ fðP l Ü T l Ü 280Þ þ P o Ü ½525 600 – ðT t Ü 280Þ – ðT l Ü 280Þâg 
60 Ü 1 000  
where:  
T l = measured time in ‘left-on mode’ for the standard cleaning cycle, in minutes and rounded to the nearest 
minute;  
280 = total number of standard cleaning cycles per year.  
(c) The standard annual energy consumption ( SAE  C ) is calculated in kWh/year as follows and rounded to two decimal 
places:  
(i) for household dishwashers with rated capacity  ps ≥ 10 and width > 50 cm:  
SAE  C = 7,0 ×  ps + 378EN 30.11.2010 Official Journal of the European Union L 314/15(ii) for household dishwashers with rated capacity  ps ≤ 9 and household dishwashers with rated capacity 9 <  ps 
≤ 11 and width ≤ 50 cm:  
SAE  C = 25,2 ×  ps + 126  
where:  
ps =  number of place settings.  
2. CALCULATION OF THE DRYING EFFICIENCY INDEX  
For the calculation of the Drying Efficiency Index ( I D ) of a household dishwasher model, the drying efficiency of the 
household dishwasher is compared to the drying efficiency of a reference dishwasher, where the reference dishwasher 
shall have the characteristics indicated in the generally recognised state-of-the-art measurement methods, including 
methods set out in documents, the reference numbers of which have been published for that purpose in the  Official 
Journal of the European Union . 
(a) The Drying Efficiency Index ( I D ) is calculated as follows and rounded to two decimal places:  
lnI D ¼ 1 
n Ü X  n 
i¼1 ln Í D T;i 
D R;i Î 
I D = exp(ln I D ) 
where:  
D T,i = drying efficiency of the household dishwasher under test for one test cycle ( i); 
D R,i = drying efficiency of the reference dishwasher for one test cycle ( i); 
n =  number of test cycles, n ≥ 5. 
(b) The drying efficiency  (D)  is the average of the wet score of each load item after completion of a standard cleaning 
cycle. The wet score is calculated as shown in Table 1:  
Table 1  
Number of water traces  (W  T ) or wet 
streak  (W  S ) Total wet area ( Aw) in mm  2 Wet score  
W T = 0 and  W  S = 0 Not applicable  2 (most efficient)  
1 < W  T ≤ 2 or  W  S = 1 Aw  < 50  1  
2 < W  T or W  S = 2 
or W  S = 1 and  W  T = 1 Aw > 50  0 (least efficient)  
3. CALCULATION OF THE ANNUAL WATER CONSUMPTION  
The annual water consumption ( AW  C ) of a household dishwasher is calculated, in litres and rounded up to the nearest 
integer, as:  
AW  C = W  t × 280  
where:  
Wt =  water consumption for the standard cleaning cycle, in litres and rounded to one decimal place.EN L 314/16 Official Journal of the European Union 30.11.2010
