2 1/2 year old dishwasher in Telegraph Cove, British Columbia for sale

My boo boo could be your gain.
I have a 2 1/2 year old Kenmore dishwasher which wasn't draining properly.We are a senior disabled couple who used it very lightly and have not used it at all for the last three months. So it should be as new.
Instead of calling someone to check it out, I replaced it. The gentleman who installed the new dishwasher noticed that the bottom of the drainage tube was dark and seemed to be clogged with dry debris . I am a disabled senior and I cannot get on my knees to remove the tube and clear it out.
If you want to purchase the unit and clear the tube ,it's yours for $ 75 OBO .If the gentleman was wrong and it's something more serious, I will give you a full refund. You can give me a post dated check (with adequate ID,) and if that is not the problem that I have stated, then you can call me within one week to come and have a look and if it's not functioning, I will return your check.
Maybe you will luck out by getting an almost new machine for only $75 OBO . And if that is not the problem, you will get your
money back.
If it is the pump, I checked on the internet. A new pump can be purchased between $49 and $69.
How can you lose?
