I do test them, briefly, while I look around, behind etc. I put the washer on the lowest water setting, warm, let it fill and start agitating, and then move the selector to "spin" to check pump-out, drain, and "balance". Maybe 5 minutes, normally. The dryer at the same time, just enough to ensure heat and no weird noises. I then report that they were run through
brief cycles and functioned normally (or not).
I learnt not to walk too far away from them early on after a water level sensor failed and the washer overflowed. Everyone had fun mopping up that mess. Vacant home, and I suspect it was a newly installed but second-hand "refurbished" unit.
After they gave me the address while still on the phone I could not find the report. It turned out they called the wrong company. After that call I think I am going to put a disclaimer about hoses on washers can not be checked or determine the life expectancy and the same about the washer and dryer.
It's not my style to clog up a report with specific disclaimers but you might want to add something about only being responsible for homes you actually inspected.
