Were you actually meaning 145 minutes or 1 hour and 45 minutes. Does the display say 1:45? I live in an all-electric house too. My water heater is set at 120, but by the time the water enters the tub, it's less than that. It is far more cost-effective to have your dishwasher or your washer heat the water as needed than keep your water heater at 140 to 150 degrees. As much as possible, I use cycles on my washer that engage the heater. For me it's whites, allergen, bulky items, and sheets. Default temperatures are hot, hotter, around 85-95 for warm respectively and I will change to hot if default is warm if the load needs it. I purposely bought a washer that will maintain water temp, and boost it, when needed as it would be4 cheaper for the washer to heat it than keep my water heater set so high. Hot is 125-127. Hotter for allergen is 130-135. Santize is 153-155 degrees. My dish loads are soiled enough it will auto temp for heavier soil at 130 or 140 degrees for the main wash. Final rinse is always 140 degrees. I don't stress about running hot or sanitize loads in my front loader like I used to with my traditional top loader. Your dryer uses more electricity to dry that load than it used to wash the load.
