After receiving a quote of more than $650 to repair an aging Bosch dishwasher, one homeowner asked whether it was worth investing in the old unit or putting that money toward a replacement.
Here's what to know
According to the owner in a Reddit thread, buying a new white-finish Bosch Series 500 would cost about $1,100 to $1,500 once installation and disposal of the old appliance were included. Their current dishwasher — an 11-year-old Series 500 — stopped draining, and a repairman said it "most likely needs a new motherboard," also known as a control board, priced at around $350 plus more than $300 in labor.
In the replies, people spent less time debating the raw repair-versus-replace cost and more time questioning whether the problem had been identified correctly.
Rather than accepting the control-board explanation, multiple commenters pointed to more routine drain problems first.
One commenter wrote: "The drain is more likely the pump or hose."
"A motherboard failure is one of the least likely causes of a drain only issue," another said.

Given the size of the estimate, at least one commenter said the owner should not move ahead without another assessment: "With the cost involved with repairing, I'd get a second opinion."
The original poster also suggested replacement was not an easy answer, citing worries about the reliability of newer dishwashers and noting that white Bosch 500 Series models were priced at a premium.
More background
A repair in the $650 region can feel especially risky when there is no guarantee it will solve the problem for good. At the same time, replacing a major appliance brings its own costs, including installation and haul-away, and it sends another large machine into the waste stream.
That doubt surfaced repeatedly in the thread, with commenters asking whether the repairman had ruled out more common drainage failures before landing on the motherboard.
Opinions on Bosch were split. One commenter praised the brand's cleaning performance and quiet operation, while another complained that a newer model did a poor job drying dishes.
What can be done?
Before agreeing to a board replacement, commenters said the owner should ask what evidence led to that diagnosis, whether an error code supports it, and if the pump or hose has already been thoroughly checked.
Others said a control-board replacement might be a realistic do-it-yourself fix for someone comfortable with appliance troubleshooting. Another advised looking up diagnostics before purchasing any parts.
Where can I learn more?
The Bosch discussion came down to whether this is a major failure or a more routine drain problem. The articles here cover that same issue, with homeowners looking for cheaper ways to clear clogs or other problems before agreeing to an expensive service call.
• A cash-strapped homeowner on Reddit tried wrapping grease in tin foil after clogging a kitchen sink.
• An expert revealed a simple trick to avoid costly dishwasher repair.
• A professional cleaner said a sink plunger saved a huge bill by clearing a stubborn drain.
If you're facing a big repair estimate, it's a useful reminder to rule out the basics first. A clog or minor blockage can be much cheaper to fix, especially when every repair dollar matters.
