Mira Elite electric shower: Water keeps running after turning it off

byrne_baby_byrn

Hi guys,

I have a problem with a Mira Elite shower that I hope you can help me with...

Whenever I turn off the unit after a shower, the water keeps coming out of it for another 5 minutes or so. It's not being pumped out by the shower unit because it still happens when I turn off the shower mains at the wall. It's as if the shower takes a few minutes to close a 'gate' or something

Any ideas? Thanks,

Jay

When finished is the shower head left on the wall or left handing down?
If its left handing down then gravity will syphon out water for a while.

Hi GreeBo,

No, there's more than gravity at play here, I'm afraid. It pretty much runs at full flow for around 5 minutes before gradually fading to a trickle and then stopping.

Weird.
Does the shower have a power knob on it?
What happens if you set that to 0?
Sounds like it might be time to call in "the man" Im afraid.

Sounds like the same problem the 'the edge' had, as 'chipclub recommended its probably the solenoid that is faulty,try the website he gave 'showerdocter.co.uk'

I'm having the same issue with a Mira at the moment - water does not stop flowing even when the power switch is off. Did you find a solution to this.

Likely to be a problem with the solenoid valve - small bits of dirt/plastic from your tank can get through the filter and hold it open. Check your warranty, if still OK then they will replace it for you. Otherwise shouldn't be too costly to get it replaced.
In the meantime, try turning it on and off quickly a few times (at full power), sometimes this blows the dirt out.

From what I know the Mira showers "empty" all the hot water left within the shower before to switch off completely. So even when you turn your shower, the water keeps running at full flow until only cold water comes out. This has been designed to avoid the next shower user to get burned when using the shower. I know it is the design for the Mira Elite that I am using.

There's some excellent uk web sites for showers and repairs...

From memory, as the poster above says there's a run on feature to flush the hot water from the heater, this normally should only take a few seconds.

Again from memory there is a little aperture inside the shower control valve that get's covered in lime scale and causes it to run on for too long. On one of the uk shower repair websites it explains how to de-scale this..

I had the same problem with my MIRA approx 1yr ago. It's just the Elite pump model (No Heater) and It turned out to be the solenoid. I just gave it a clean and a bit of WD40. No issue since.

I have the same problem with a Mira Elite that I bought a year ago.

It has now gone on the blink for the third time since it was installed.

Whereas previously it would eventually turn off after about 10 or 15 mins, it now won't turn off at all. And unless the pull string switch is turned off, it continues to pump hot water ( even if the shower switch itself is turned off).

I have made a temporary fix by unscrewing the shower head and placing a one cent coin behind the rubber washer in the shower head - hose junction nd screwing back on the shower head. perfect fit

The company that Mira support in Dublin have been less than helpful and friendly!:(

When I made my latest complaint this morning to the local shop where I originally bought it I was informed that this is a "known problem" with the Mira Elite.

Hey all. Currently having the same problem with a Mira EventXS. Have called the Mira people in Ireland but they say they may not be able to look at it for 3 days!!!! :eek:

Can anyone recommend a plumber/shower maintenance guy to fix this for me?

Help appreciated.

Have same problem as others have described here ie. Elite ST that continues to allow water to run after show has been switched off. Its getting worse and now will not stop flowing at all. Have used the old 1 cent trick to stop the flow for the moment.

Opened up shower unit and checked filter (limescale a major problem in this area) but it was clean. Not sure if theres anything else I can do? Will call the 'service' line tomorrow morning as its still within 1 year of purchase and have receipt.
@George/Western Cruiser: How did they fix and was it covered under your 1 year warranty?

GeorgeCostanza

The problem is caused by a solenoid failing. (solenoid is the electrical component that controls the valves). I got a plumber out to replace it, 150 euro in all.

The shower is 5 years old so it was not covered under warranty.

What's the 1 cent trick??

Is a temporary measure suggested by Western Cruiser above to stock the flow of water until the unit can be repaired.
Going to ring for warranty repair today and see how I get on...

For Example for my Mira Elite ST the pdf is:
http://www.mirashowers.com/onlinecatalog/pdf/1056830_w2_g_mira_elite_st.pdf

In it there is a FAULT DIAGNOSIS section w/trouble shooting info containing details on probable causes and remedies should difficulties be encountered whilst the shower is in operation. In this case:
Symptom: Water will not turn off
Power Light: is on
Low Flow Light: is off
Heater setting (Low / Med / High): MED / HIGH
Probable Cause: Flow Valve, Solenoid or Start/Stop switch faulty.
Possible Remedy: Replace Parts as Required

Unless you aren't getting any power to the unit at all, it's more than likely as below:

NOTE*: 10.8 kW flow valves and 10.8 kW heater tanks are not interchangeable with 9.8 kW models. The fitting of 10.8 kW spares on 9.8 kW models will void the warranty on the product. The following relevant parts are listed in the installation/User Guide:
1563.748 P/C Flow Valve Assembly 9.8 kW* or 1563.749 P/C Flow Valve Assembly 10.8 kW*
416.51 Solenoid Coil Assembly. The flow valve assembly already includes a solenoid, so there's no need to order both parts if you are going to replace the entire flow valve assembly.

showerspares.com & showerdoc.com list the following for the flow valve assembly for the 9.8 kw unit as: Mira 1563.507 - Flow valve assembly (£34.83 & £34.91)
(this part is not listed in the mira elite ST parts list in the install guide, but appears to be the 9.3kw flow valve assembly), as the Heater Tank in the same parts list is also 9.8 kw and matches the Mira installation guide part # (1563 504). Also I see no reference to a 10.3kw parts on either web site.

Seems Elite spares = Sport or Sport Max Spares, on the Mira home site (under the spare parts link):
Part #1563.507 is actually the Mira Sport Flow Valve (from 1999 onwards) price from Mira - £35.36
Part #1563.508 for Mira Sport Max Flow Valve is a 10.8 kw unit & is logically the appropriate 10.8 kw replacement part as it looks like they have standardized the parts even at Mira & the Elite ST is still on offer from the website in both 9.8 kw & 10.8 kw options. The 10.8 kw unit sells for £47.83 from Mira. Some additional parts may be needed depending on the model year. I called showerdoc.com technical support in Scotland and they were able to verify my requirements.

While it's possible to change out the solenoid alone it's considered best to replace the entire flow valve with solenoid.

Mira 416.51 - Solenoid coil (£16.22 & £12.60) is listed on both sites the same as the Mira installation/User Guide (don't see the solenoid listed on the Mira home website though).

Good Luck

stupid question

how do you check the warranty, do you have to have the paperwork and the receipt, as i never keep those. Is there a serial number or are you screwed without a receipt. Mine is only 18 months old its my third mira shower in 7 years.

I've cleaned the filters on mine and added a calgon tablet to the water tank, anyway I have a different problem with my units, but the warranty issue is relevant.

I just did the 1 cent trick Western Cruiser did...

Hope that's ok to do that? Nothing will blow up will it?

I'll use the bath thingy till I can get a plumber...
