Using hot water input for dishwasher or washing machine

[grin]

We have solar hot water running to all of our bathrooms, kitchen, and laundry room. Currently our dishwasher and washing machine are fed from cold water taps. Both of these appliances obviously have heating elements for the water. They do expect cold water input as indicated in both manuals. I was considering hooking up hot water to the dishwasher to see if it would speed up the cycles. This would also save some energy costs. I would expect that the hose might need to be changed for hot water but was thinking that using hot water might affect the programming adversely. Any ideas on pros and cons of doing this?

Unless you have excessively hot water (over 50^oC) then no changes are normally needed to the supply pipe possibly until you go over 75^oC. Since the incoming cold supply in Thailand can vary between about 4^oC and north of 30^oC A hot water supply is not going to effect the programming.
