extreme thermal and aquatic conditions. ŸExterior should be made of an electrically insulating material such as plastic. Wooden cover on door for mahogany effect. There should also be a sound proofing material surrounding the machine to reduce noise pollution. ŸDoor should open easily with little force required. The operation switches and knobs should be easy to understand. Instructions and cycle instructions should be basic and direct. Cost is also important, it needs to reflect the product’s features and be within a price band that is accessible to most people. Questionnaire No. surveyed 1.

Do you believe the product has enough user features? 1. 2. 3. Yes No 7. Is the product easy to carry out general maintenance on 1. 2. 3. I.e. clean filters etc.? Yes No 8. Are the stacking arrangements of the baskets adequate for 1. 2. 3. the average household? Yes No 9. Does the purchase price of this dishwasher reflect the overall 1. 2. 3. quality and features of the product? Yes No Evaluation Materials: The interior tub is made of high grade stainless steel suitable for extreme aquatic and thermal conditions. The exterior is made of heat resistant polyvinyl chloride with the outer casing

consisting of rust treated steel as condensation can form on surface of washer. There is also a sound dampening material on machine to reduce noise pollution. All materials are well suited to job. Safety: The machine has been in the household for 8 years and has not caused an accident in its working life. No electrical components are exposed to metal or damp areas however there is a slot in the door where a lot of wire is run through. Buttons can sometimes catch the skin and nip. All sharp areas are covered but there are areas where fingers could get caught. Over heat thermostats are installed to switch off heaters when water reaches 75oC. All metal parts are earthed and there is a 13 amp fuse in pug top. The spring switch in the door can be stiff and slips which may cause

serious accidents. Ergonomics: This machine is quite easy to use, but some symbols can be confusing. The machine has a counter balance door for easy opening and an ‘easy grip’ control knob for easier operation. The interior of the machine includes an ‘easy lift’ upper basket. Door tends to stick at times. Also the symbols on the knob often wear off with time and use. Appearance: It is fairly dark and dull. It integrates well with the mahogany kitchen as a wood panel door has been fitted. It also has a brown control panel which adds to its unattractiveness. The control panel is easily cleaned however. Modification 1. I would modify the door mechanism. It can be quite stiff at times and needs to be adjusted to loosen spring slightly as I have mentioned in the evaluation. 2.

I would also modify the timer knob of the washer as sometimes it is difficult to know what cycle the dishwasher is in because the letters wear off. 3. The appearance I think needs to be improved as the machine is fairly dull and dreary. It needs brightened up. Wash progression L.E.D.’s would brighten up the control panel and be a source of information for the user. 4. I would also route the main wiring harness up the back of the dishwasher instead of its current position via the door. This would prevent wires breaking due to fatigue caused by the door opening and closing over the course of its working life.
