The customer service leaves a lot to be desired, very unfriendly people! Call 1st time for an explanation of an error code. Does the gentleman on the phone start explaining that this is not their job and that they can only make arrangements for the technician and the rest cannot do anything. Looking up a simple error code is not even possible with them, because there is no technical service that can be called for more explanation. Also looking up on the basis of a serial number whether the warranty is still valid is not possible. When we call a second time to make an appointment, they are unfriendly and immediately ask for the zip code and surname without asking for the address. Ask me why they don't just start with the name and address. They also ask for the purchase date. I kindly explain that we don't know this since it belonged to a showroom model of a kitchen. The gentleman starts to swear at me and that he doesn't have to know all that and that they don't care and they are only interested in the date of purchase. I have only given the date when we have purchased the full kitchen. The only plus point is that they can immediately come by tomorrow to carry out the repair. Wondering how this will go and whether this is still within the warranty or not.

EDIT: the technician was very friendly, unfortunately he could not do anything since it apparently was a production error and a known problem within whirlpool. Apparently the customer service is also managed externally and whirlpool itself cannot do much about its customer friendliness. They have blamed the external company several times for customer friendliness.
