I recently had a 6 month old dishwasher repaired under warranty. The contracted repairer returned the dishwasher one week later covered with bloody hand prints. There is also a small amount of blood inside the dishwasher. We were not home when the dishwasher was returned. The repairer does not remember specifically bleeding on our appliance but said he could have because he "cuts himself all the time". When we went to the store we bought the dishwasher from they were quite dismissive of our concerns about blood borne disease. Is it unreasonable not to want to use a kitchen appliance contaminated with a strangers blood?
