Can someone offer legitimate advice on BAD Landlord?

[JAhuman2]

I've moved into a Townhome in N. Las Vegas (from N. CA) to be near my Mother who was diagnosed with Dementia/Alzheimer's. Anyway, since I had to "demand" this Owner/Landlord to fix the Refrigerator that needed a motor for the internal cooling fan ($370.00) in order to keep my food fresh - he now expects me to "repair" the laundry Washing Machine he provided with the property. Last night he cited the section in the Lease that states "Tenant assumes responsibility for the care and maintenance thereof" referring to appliances such as the Washer/Dryer and it even refers to the Refrigerator he already fixed. Now, this Owner/Landlord has told me that I am responsible to "repair" the 11 year old Washer that broke down yesterday. The Water Level Sensor stopped working and the unit overfilled. Water flooded the unit. This happened 5 days after I warned him about the Water Level Sensor malfunction, and he chose to ignore this fact. Please confirm that I am not responsible to repair this man's old worn out Washing machine! ///
Now this Landlord has decided to sick his Attorney's on me. Just because I requested he "repair" his Washing machine. He supplied an 11 year old (abused) Washing machine as a part of the 2 year Lease. I alerted him about the poor condition/performance of this Washing machine just 2 days after taking up residence in his property. Please, someone offer legitimate advice!
