The water discharge line is connected to a unit that is mounted to the sink. This unit in turn has another line that is connected the the house drain. This unit is sparying all over the sink, counter and floor. What is the purpose of this unit and why couldn't the drain from the dishwasher be connected directly to the house drain?

It is a unit to stop water flowing back into the Washer... I suspect it is blocked... You probably need a Plumber?

Clogged Bosch SHU 9920 dishwasher

-Sounds like the pump is not working properly or the drain line you connect to sink directly instead to the breath cap before to the sink. Or the breath cap locate too low.
-Make sure the breath cap is mount higher than the line to the sink. (Or as high as possible) This is to prevent any water from the sink pour into the dishwasher.

Good luck

This dish washer has a hose going to the top of the sink then it go to the garbage disposal. Well now when it starts to drain water shoots out real fast out of the part that is on the sink, it never did...

Sounds like something is damaged in the vacuum break device on top of your sink. Unscrew the chrome housing and see what you see. I would expect to see a pipe coming from the dishwasher, come into this unit, turn 180 degrees and discharge into an open chamber that is connected to the hose going to the garbage disposer. It is possible that this hose is plugged, so verify it is open into the dipsoser.

It is likely that you will need to replace this device, as it is serviced as a whole unit..... it's job is to keep sewage water from being drawn back into the dishwasher.

My sanivite 3 has a washer connected to the bottom inlet and a sink to the top inlet. when water is run from the sink the system will pump the water out, however when the washer is discharging waste the...

A washing machine discharges water water at a very high velocity and high capacity. This is far more waste water than the pump was designed to handle. The washer discharge must be connected to what's called an "indirect waste", that is, it must discharge into a laundry tub or sump, so that the excess can be stored until it can be taken by the pump. The specific code that governs this is in chapter 27 of the International Residential Code.

Also in the manufacturers instructions, they allow the discharge from a washing machine ,through an indirect waste. [sic] "The Sanivite is a drain pump that is ideally suitable for use in a basement apartment or anywhere in the house where additional fixtures are most wanted. It will pump waste water away from a variety of sources such as: a kitchen sink, laundry sink, washing machine ***(indirect connection)***, dishwasher, bar sink, etc."

This pump will never be able to handle the discharge directly and you need to provide a receptor to accommodate a washing machine. Is there any possibility of adding a laundry tub adjacent the washer and Sanivite pump?

Water is coming out of air flow gap. I installed a new air-flow gap and all new lines from air flow gap to sink (except the line from dishwasher to air flow gap) and i still have water coming out the air...

The leak in an air gap is usually caused by a clogged sink discharge line. Most of the time this is connected to the garbage disposal and there is food particulate in the drain hole where the dishwasher drain from the air gap to the garbage disposal connects.

Pull the sink connection hose off and clean the hole thoroughly. You can try testing the dishwasher/ air gap by placing the disconnected hose into a bucket during the pump out period. It should not leak. After this test...reconnect the hose to the sink connection.

If it is NOT connected to the garbage disposal then remove the hose and clean out the hole where the connection is made. This is a common problem and easily resolved by the user.

Thanks for using FixYa.

Dishwasher just over a year old. Very slow to

The little white balls are check valves - you need them.

Have you checked the discharge check valve under the dishwasher where the discharge line connects to the sink? It is under the unit and can be unscrewed (carefully). The valve can be disassembled with a couple of pronged keepers. This check valve can become obstructed and cause the problem you decscribe.

Dishwasher won't drain, the pump seems to be working but it's like it's clogged or something, any ideas?

OK, first using a sponge and bucket, drain out all the water of the dishwasher (DW) as you can. You can also use a towel too.

Check the discharge/drain cover at the bottom of the DW for any obstructions. Sometimes small pieces of all sorts of things get sucked into the drain port.

There should be a protective shroud/cover over the drain and you might have to remove a small hex head screw to get into the drain sump inlet. Some can be popped off without any tools.

Once you have the cover off, be VERY careful in probing the drain area trying to see if there are any small broken pieces of dishes or glasses that may have gotten into the sump area. You'll want to use a towel or sponge to get the water out of the sump area.

If you don't get anything out of the sump drain, it could be that the obstruction has worked its' way into the motor disposal impeller and you'll have to remove the DW from under the counter in order to get at the motor and pump assembly. This will require possible disconnection of the water supply line, AC power line or plug, and the drain line going to the sink or disposal.

Before getting into removing the DW, you can also check the drain line for blockage by disconnecting it from either the sink drain connection or disposal and blow into the line. If it's not clogged, you'll get air coming into the DW. If not, then the drain line is clogged. Also check the Air break connection, mounted on the sink, (if so equipped) and clean it out. You can also pour warm water down the Air break to verify that the line is clear.

If this doesn't work, please check my other solutions under dishwashers for a complete step-by-step for getting to the discharge pump section.

I've seen blockages occur fairly often on these models and it's usually caused by broken bits getting into the discharge pump and jamming the impeller. Once removed, normally the DW will work fine, unless the impeller has been totaly chewed up by the blockage, then you may have to replace the discharge impeller to get it able to pump out properly.

Hope you found this very helpful and best regards!

Check the following:

Debris that may be interfering with the drain in the bottom of the dishwasher - especially if the unit has a soft disposal. You may have to remove the lower wash arm and housing cover.

Check the drain line and be sure it's clear to the sink drain spur and that there are no kinks or other obstructions

Check the check valve on the discharge from the dishwasher - even small obstructions can cause this valve to plug or jam -this usually requires removal of the front lower panel - look for the drain line connection to the dishwasher - the check valve is usually screwed into a housing. Be careful un-screwing it. You may need a shallow pan to drain water into when you remove the drain line and check valve if there is still water in the dishwasher

It also could be the pump, but check all of the above first.

Finally, it could be the circuit board, but you didn't indicate there were any other problems with the dishwasher other than the drain
