Yesterday opened the door to dishwasher, and heard a thud sound. Now the door weighs a ton. I believe a spring/bracket broke, but can find no evidence of it. The dishwasher is working properly....the door just is very heavy....not normal. Can this be repaired? Cheaply? This is a model MDB4000AWA Serial 18135973WH

You will need to pull the dishwasher out about 12" to 18" to be able to get to the springs & rope links. Many dishwashers use a "rope link" to connect between the spring and the door hinge; and in others, the door springs connect directly to the door hinges. Once you pull the dishwasher out, you will easily see what broke and what you need to fixe it.

It sounds like the spring which tensions the idler pulley has come off the bracket. You'll need to locate it and put it back on.

Believe it or not; a good firm ****. Whats broke is already broke.

One or both of the door springs came off or broke. If you take off the bottom panel you should be able to look with a flashlight and see.You can buy the springs and replace them.

the spring either came unhooked or otherwise fell off - you should be able to unhook the mounting bracket, lower the front legs and pull the machine out a bit -- BE CAREFUL TO SEE YOU HAVE ENOUGH LENGTH OF WATER LINE, DRAIN AND ELECTRICAL BEFORE YOU MOVE IT OUT - once you gain access, check alongside the machine you will find your problem..

Open the back door and see whether the hooking points visible.

Look from the front end also to get an idea!

well it sounds like you broke a spring,possably a cable you nooe to take off the bottom cover to find what broke.

Murray, It sounds like one of the door springs has broken and that is why the door seems heavier and opens with much more force.

You'll want to at least make a temporary repair and order a new replacment spring to get your dishwasher working like it should and so it's safer too.

You can check to see which side of the dishwasher the spring broke, by locking the door shut (with the cycle set to "off"). Now remove the lower access panel, beneath the main dishwasher door. There are a couple of screws near the top corner edges of the panel, just under the main door and a couple more on the toe kick near the very bottom.

Once you've got the lower access panel off, you'll be able to see the two door springs, (there is one on each side). Of course, the broken one might have fallen off the spring notches, so look around and you should see it.

With the door still closed and locked, you can remove the broken spring and see if it's just the hook end that broke. If that's the case, you can reform the end hook using a couple pairs of pliers and reinstall the spring on the door and frame mounting points. You'll have to use pliers to stretch the spring slightly to get it on the other mounting point, once you've got one end on a mounting point. If the spring broke off more than 3 coils, you'll need to replace it with a new one.

You can find a replacement by using searspartsdirect.com and putting in your model number to locate a line drawing and parts listing for your particular model. You can also order a new one from them, or use the part number to get one locally, if you wish.

Once you've got the spring back on the door and cabinet mount points, you can unlock the door and gently lower the door to see if everything is working properly. Once you've opened and closed the door several times, you can reinstall the lower access panel and you're back in business.

I hope you find this Very Helpful and best regards!

You're right a spring has either snapped or come off of it's anchor point. Should be 2 ...one on each side of the door. you can order parts on line at several appliance replacement part suppliers... have your make and model so you'll get the right parts. K

My dishwasher model DU3003XL0 has a similar problem. It happened yesterday. I had opened the door all the way, and then I heard a loud clunk sound. I suspect it is the spring mechanism in the door, and am ordering new springs, and hope to fix it myself.
Wish me luck.
