I have been using Dawlance 7 kg 15-A model in KHI for last 3 years which I bought for 33k I guess from Johar Mor back then (production of this model is discontinued now) and have been using SAMSUNG TOP LOAD FULLY AUTOMATIC WASHING MACHINE 9KG + 1KG (WA90J5710SG) for last 6 months in LHE which was bought in 48k from Abid Market. I would suggest you to go to Abid market, metro, Hyperstar etc. and have a look on machines of all models. You'll find that imported ones (Samsung, Kenwood etc.) have the finest build quality as compared to the local ones (Dawlance, Hair etc.). I got no issue running both machines so far but from the build quality I assume that Samsung (or Kenwood) ought to be more durable as compared to Dawlance (or Hair).
So I would suggest you to go for imported ones like samsung. 7 Kg should be enough for you. I have even run my 7 kg machine on UPS 720 watts (1000 VA).
